Spring Data JDBC 详解

Mon, 28 Dec 2015 15:48:00 GMT
spring data �p�d��一直是开发者追捧的热潮�Q�而官方�ƈ未出spring data jdbc�Q�国外一个开发者让我们看到了福韻I��文��如下供大家共同学习�?br />

Spring Data JDBC generic DAO implementation

The purpose of this project is to provide generic, lightweight and easy to use DAO implementation for relational databases based on JdbcTemplate from Spring framework, compatible with Spring Data umbrella of projects.

Design objectives

Lightweight, fast and low-overhead. Only a handful of classes, no XML, annotations, reflection

This is not full-blown ORM. No relationship handling, lazy loading, dirty checking, caching

CRUD implemented in seconds

For small applications where JPA is an overkill

Use when simplicity is needed or when future migration e.g. to JPA is considered

Minimalistic support for database dialect differences (e.g. transparent paging of results)

Features

Each DAO provides built-in support for:

Mapping to/from domain objects through RowMapper abstraction

Generated and user-defined primary keys

Extracting generated key

Compound (multi-column) primary keys

Immutable domain objects

Paging (requesting subset of results)

Sorting over several columns (database agnostic)

Optional support for many-to-one relationships

Supported databases (continuously tested):

MySQL

PostgreSQL

H2

HSQLDB

Derby

MS SQL Server (2008, 2012)

Oracle 10g / 11g (9i should work too)

...and most likely many others

Easily extendable to other database dialects via SqlGenerator class.

Easy retrieval of records by ID

API

Compatible with Spring Data PagingAndSortingRepository abstraction, all these methods are implemented for you:

public interface PagingAndSortingRepository extends CrudRepository { T save(T entity); Iterable save(Iterable entities); T findOne(ID id); boolean exists(ID id); Iterable findAll(); long count(); void delete(ID id); void delete(T entity); void delete(Iterable entities); void deleteAll(); Iterable findAll(Sort sort); Page findAll(Pageable pageable); Iterable findAll(Iterable ids); }

Pageable and Sort parameters are also fully supported, which means you get paging and sorting by arbitrary properties for free. For example say you have userRepository extending PagingAndSortingRepository interface (implemented for you by the library) and you request 5th page of USERS table, 10 per page, after applying some sorting:

Page page = userRepository.findAll( new PageRequest( 5, 10, new Sort( new Order(DESC, "reputation"), new Order(ASC, "user_name") ) ) );

Spring Data JDBC repository library will translate this call into (PostgreSQL syntax):

SELECT * FROM USERS ORDER BY reputation DESC, user_name ASC LIMIT 50 OFFSET 10

...or even (Derby syntax):

SELECT * FROM ( SELECT ROW_NUMBER() OVER () AS ROW_NUM, t.* FROM ( SELECT * FROM USERS ORDER BY reputation DESC, user_name ASC ) AS t ) AS a WHERE ROW_NUM BETWEEN 51 AND 60

No matter which database you use, you'll get Page object in return (you still have to provide RowMapper yourself to translate from ResultSet to domain object). If you don't know Spring Data project yet, Page is a wonderful abstraction, not only encapsulating List, but also providing metadata such as total number of records, on which page we currently are, etc.

Reasons to use

You consider migration to JPA or even some NoSQL database in the future.

Since your code will rely only on methods defined in PagingAndSortingRepository and CrudRepository from Spring Data Commons umbrella project you are free to switch from JdbcRepository implementation (from this project) to: JpaRepository, MongoRepository, GemfireRepository or GraphRepository. They all implement the same common API. Of course don't expect that switching from JDBC to JPA or MongoDB will be as simple as switching imported JAR dependencies - but at least you minimize the impact by using same DAO API.

You need a fast, simple JDBC wrapper library. JPA or even MyBatis is an overkill

You want to have full control over generated SQL if needed

You want to work with objects, but don't need lazy loading, relationship handling, multi-level caching, dirty checking... You need CRUD and not much more

You want to by DRY

You are already using Spring or maybe even JdbcTemplate, but still feel like there is too much manual work

You have very few database tables

Getting started

For more examples and working code don't forget to examine project tests.

Prerequisites

Maven coordinates:

com.nurkiewicz.jdbcrepository jdbcrepository 0.4

This project is available under maven central repository.

Alternatively you can download source code as ZIP.

In order to start your project must have DataSource bean present and transaction management enabled. Here is a minimal MySQL configuration:

@EnableTransactionManagement @Configuration public class MinimalConfig { @Bean public PlatformTransactionManager transactionManager() { return new DataSourceTransactionManager(dataSource()); } @Bean public DataSource dataSource() { MysqlConnectionPoolDataSource ds = new MysqlConnectionPoolDataSource(); ds.setUser("user"); ds.setPassword("secret"); ds.setDatabaseName("db_name"); return ds; } }

Entity with auto-generated key

Say you have a following database table with auto-generated key (MySQL syntax):

CREATE TABLE COMMENTS ( id INT AUTO_INCREMENT, user_name varchar(256), contents varchar(1000), created_time TIMESTAMP NOT NULL, PRIMARY KEY (id) );

First you need to create domain object User mapping to that table (just like in any other ORM):

public class Comment implements Persistable { private Integer id; private String userName; private String contents; private Date createdTime; @Override public Integer getId() { return id; } @Override public boolean isNew() { return id == null; } //getters/setters/constructors/... }

Apart from standard Java boilerplate you should notice implementing Persistable where Integer is the type of primary key. Persistable is an interface coming from Spring Data project and it's the only requirement we place on your domain object.

Finally we are ready to create our CommentRepository DAO:

@Repository public class CommentRepository extends JdbcRepository { public CommentRepository() { super(ROW_MAPPER, ROW_UNMAPPER, "COMMENTS"); } public static final RowMapper ROW_MAPPER = //see below private static final RowUnmapper ROW_UNMAPPER = //see below @Override protected S postCreate(S entity, Number generatedId) { entity.setId(generatedId.intValue()); return entity; } }

First of all we use @Repository annotation to mark DAO bean. It enables persistence exception translation. Also such annotated beans are discovered by CLASSPATH scanning.

As you can see we extend JdbcRepository which is the central class of this library, providing implementations of all PagingAndSortingRepository methods. Its constructor has three required dependencies: RowMapper, RowUnmapper and table name. You may also provide ID column name, otherwise default "id" is used.

If you ever used JdbcTemplate from Spring, you should be familiar with RowMapper interface. We need to somehow extract columns from ResultSet into an object. After all we don't want to work with raw JDBC results. It's quite straightforward:

public static final RowMapper ROW_MAPPER = new RowMapper() { @Override public Comment mapRow(ResultSet rs, int rowNum) throws SQLException { return new Comment( rs.getInt("id"), rs.getString("user_name"), rs.getString("contents"), rs.getTimestamp("created_time") ); } };

RowUnmapper comes from this library and it's essentially the opposite of RowMapper: takes an object and turns it into a Map. This map is later used by the library to construct SQL CREATE/UPDATE queries:

private static final RowUnmapper ROW_UNMAPPER = new RowUnmapper() { @Override public Map mapColumns(Comment comment) { Map mapping = new LinkedHashMap(); mapping.put("id", comment.getId()); mapping.put("user_name", comment.getUserName()); mapping.put("contents", comment.getContents()); mapping.put("created_time", new java.sql.Timestamp(comment.getCreatedTime().getTime())); return mapping; } };

If you never update your database table (just reading some reference data inserted elsewhere) you may skip RowUnmapper parameter or use MissingRowUnmapper.

Last piece of the puzzle is the postCreate() callback method which is called after an object was inserted. You can use it to retrieve generated primary key and update your domain object (or return new one if your domain objects are immutable). If you don't need it, just don't override postCreate().

Check out JdbcRepositoryGeneratedKeyTest for a working code based on this example.

By now you might have a feeling that, compared to JPA or Hibernate, there is quite a lot of manual work. However various JPA implementations and other ORM frameworks are notoriously known for introducing significant overhead and manifesting some learning curve. This tiny library intentionally leaves some responsibilities to the user in order to avoid complex mappings, reflection, annotations... all the implicitness that is not always desired.

This project is not intending to replace mature and stable ORM frameworks. Instead it tries to fill in a niche between raw JDBC and ORM where simplicity and low overhead are key features.

Entity with manually assigned key

In this example we'll see how entities with user-defined primary keys are handled. Let's start from database model:

CREATE TABLE USERS ( user_name varchar(255), date_of_birth TIMESTAMP NOT NULL, enabled BIT(1) NOT NULL, PRIMARY KEY (user_name) );

...and User domain model:

public class User implements Persistable { private transient boolean persisted; private String userName; private Date dateOfBirth; private boolean enabled; @Override public String getId() { return userName; } @Override public boolean isNew() { return !persisted; } public void setPersisted(boolean persisted) { this.persisted = persisted; } //getters/setters/constructors/... }

Notice that special persisted transient flag was added. Contract of [CrudRepository.save()](http://static.springsource.org/spring-data/data-commons/docs/current/api/org/springframework/data/repository/CrudRepository.html#save(S)) from Spring Data project requires that an entity knows whether it was already saved or not (isNew()) method - there are no separate create() and update() methods. Implementing isNew() is simple for auto-generated keys (see Comment above) but in this case we need an extra transient field. If you hate this workaround and you only insert data and never update, you'll get away with return true all the time from isNew().

And finally our DAO, UserRepository bean:

@Repository public class UserRepository extends JdbcRepository { public UserRepository() { super(ROW_MAPPER, ROW_UNMAPPER, "USERS", "user_name"); } public static final RowMapper ROW_MAPPER = //... public static final RowUnmapper ROW_UNMAPPER = //... @Override protected S postUpdate(S entity) { entity.setPersisted(true); return entity; } @Override protected S postCreate(S entity, Number generatedId) { entity.setPersisted(true); return entity; } }

"USERS" and "user_name" parameters designate table name and primary key column name. I'll leave the details of mapper and unmapper (see source code). But please notice postUpdate() and postCreate() methods. They ensure that once object was persisted, persisted flag is set so that subsequent calls to save() will update existing entity rather than trying to reinsert it.

Check out JdbcRepositoryManualKeyTest for a working code based on this example.

Compound primary key

We also support compound primary keys (primary keys consisting of several columns). Take this table as an example:

CREATE TABLE BOARDING_PASS ( flight_no VARCHAR(8) NOT NULL, seq_no INT NOT NULL, passenger VARCHAR(1000), seat CHAR(3), PRIMARY KEY (flight_no, seq_no) );

I would like you to notice the type of primary key in Persistable:

public class BoardingPass implements Persistable { private transient boolean persisted; private String flightNo; private int seqNo; private String passenger; private String seat; @Override public Object[] getId() { return pk(flightNo, seqNo); } @Override public boolean isNew() { return !persisted; } //getters/setters/constructors/... }

Unfortunately library does not support small, immutable value classes encapsulating all ID values in one object (like JPA does with @IdClass), so you have to live with Object[] array. Defining DAO class is similar to what we've already seen:

public class BoardingPassRepository extends JdbcRepository { public BoardingPassRepository() { this("BOARDING_PASS"); } public BoardingPassRepository(String tableName) { super(MAPPER, UNMAPPER, new TableDescription(tableName, null, "flight_no", "seq_no") ); } public static final RowMapper ROW_MAPPER = //... public static final RowUnmapper UNMAPPER = //... }

Two things to notice: we extend JdbcRepository and we provide two ID column names just as expected: "flight_no", "seq_no". We query such DAO by providing both flight_no and seq_no (necessarily in that order) values wrapped by Object[]:

BoardingPass pass = boardingPassRepository.findOne(new Object[] {"FOO-1022", 42});

No doubts, this is cumbersome in practice, so we provide tiny helper method which you can statically import:

import static com.nurkiewicz.jdbcrepository.JdbcRepository.pk; //... BoardingPass foundFlight = boardingPassRepository.findOne(pk("FOO-1022", 42));

Check out JdbcRepositoryCompoundPkTest for a working code based on this example.

Transactions

This library is completely orthogonal to transaction management. Every method of each repository requires running transaction and it's up to you to set it up. Typically you would place @Transactional on service layer (calling DAO beans). I don't recommend placing @Transactional over every DAO bean.

Caching

Spring Data JDBC repository library is not providing any caching abstraction or support. However adding @Cacheable layer on top of your DAOs or services using caching abstraction in Spring is quite straightforward. See also: @Cacheable overhead in Spring.

Contributions

..are always welcome. Don't hesitate to submit bug reports and pull requests.

Testing

This library is continuously tested using Travis (). Test suite consists of 60+ distinct tests each run against 8 different databases: MySQL, PostgreSQL, H2, HSQLDB and Derby + MS SQL Server and Oracle tests not run as part of CI.

When filling bug reports or submitting new features please try including supporting test cases. Each pull request is automatically tested on a separate branch.

Building

After forking the official repository building is as simple as running:

$ mvn install

You'll notice plenty of exceptions during JUnit test execution. This is normal. Some of the tests run against MySQL and PostgreSQL available only on Travis CI server. When these database servers are unavailable, whole test is simply skipped:

Results : Tests run: 484, Failures: 0, Errors: 0, Skipped: 295

Exception stack traces come from root AbstractIntegrationTest.

Design

Library consists of only a handful of classes, highlighted in the diagram below (source):

JdbcRepository is the most important class that implements all PagingAndSortingRepository methods. Each user repository has to extend this class. Also each such repository must at least implement RowMapper and RowUnmapper (only if you want to modify table data).

SQL generation is delegated to SqlGenerator. PostgreSqlGenerator. and DerbySqlGenerator are provided for databases that don't work with standard generator.

mongdb 使用linux shell修改数据

Tue, 22 Sep 2015 11:25:00 GMT
1、编写脚步：update.js
/**
* 旉��对象的格式化;
*/
Date.prototype.format = function(format) {
/*
* eg:format="YYYY-MM-dd hh:mm:ss";
*/
var o = {
"M+" :this.getMonth() + 1, // month
"d+" :this.getDate(), // day
"h+" :this.getHours(), // hour
"m+" :this.getMinutes(), // minute
"s+" :this.getSeconds(), // second
"q+" :Math.floor((this.getMonth() + 3) / 3), // quarter
"S" :this.getMilliseconds()
// millisecond
}

if (/(y+)/.test(format)) {
format = format.replace(RegExp.$1, (this.getFullYear() + "")
.substr(4 - RegExp.$1.length));
}

for ( var k in o) {
if (new RegExp("(" + k + ")").test(format)) {
format = format.replace(RegExp.$1, RegExp.$1.length == 1 ? o[k]
: ("00" + o[k]).substr(("" + o[k]).length));
}
}
return format;
}
var date =new Date();
var createdate=date.format("yyyy-MM-dd hh:mm:ss");
date.setMinutes(date.getMinutes()+5);
var validtime=date.format("yyyy-MM-dd hh:mm:ss");
db.UserOnlineInfo.update(
{
"uid" : "110000350"
},
{$set : {
"uid" : "110000350",
"createtime" : createdate,
"validtime" : validtime
}});
db.UserOnlineInfo.update(
{
"uid" : "110000351"
},
{$set : {
"uid" : "110000351",
"createtime" : createdate,
"validtime" : validtime
}});

2、编写shell脚步�Q?br /> #/bin/bash
echo "update mongod begin"
cd /home/mongodb/mongodb-3.0.2/bin
./mongo 192.168.1.122:27108/YouLiao update.js;
echo "update mongod success"

3�?执行脚本�Q?/div>
/home/mongodb/mongodb-3.0.2/bin/mongo 192.168.1.122:27108/YouLiao /root/www/job/mongo-test/update.js

备注�Q?/div>
mongodb查询、删除类�?/div>
