Spring IDE Guide

冰雨 — Tue, 25 Apr 2006 07:10:00 GMT

Spring IDE Guide ¶

From: http://springide.org/project/wiki/SpringideGuide

To start working with Spring IDE you need a SpringProject. A SpringProject can be created by adding the SpringProjectNature to an existing project or by creating a new Spring project with the SpringProjectWizard.

Add SpringProject nature ¶

select open project nodes in Eclipse resource navigator or JDT package explorer
activate context menu item "Add Spring Project Nature" on selected projects

once the nature is added, these projects are now decorated with a small 'S' in the upper right corner (overwriting other decorators, e.g. Java project decorator 'J')

to remove the nature, right click the project and select "Remove Spring Project Nature"

Create new SpringProject ¶

open the wizard selection dialog via the menu "File / New / Project..."

select the wizard "Spring IDE / New Spring Project"

enter the project name
(optionally) modify the comma-separated list of supported BeansConfig file extensions (default is "xml")
if you don't need a Java project then deselect the checkbox "Create a Java project"
for a Java project you can change the project's settings (source / classes folder, classpath, libraries, ...) on the next dialog page

Add references to other Spring projects (optional) ¶

open a Spring project's properties dialog from the context menu in Eclipse resource navigator or JDT package explorer
select the properties page "Project References" from the list on the left side
enable all Spring project(s) containing Spring Beans config files which are referenced from within this project via Spring Beans config sets (defined later on)

Add Spring BeansConfig files ¶

open a Spring project's properties dialog from the context menu in Eclipse resource navigator or JDT package explorer
select the properties page "Spring Beans" from the list on the left side

(optionally) modify the comma-separated list of supported BeansConfig file extensions (default is "xml")
use the button "Add..." to open a selector dialog providing a list of all files with the specified extensions in your Spring project and select the corresponding Spring BeansConfig files

once the config files are selected the corresponding files are decorated with a small 'S' in Eclipse resource navigator or JDT package explorer

Create Spring BeansConfig file sets (optional) ¶

open a Spring project's properties dialog from the context menu in Eclipse resource navigator or JDT package explorer
select the properties page "Spring Beans" from the list on the left side
select the second tab labeled "Config Sets"

use the button "New..." to open a dialog for creating a new config set with a selection of all config files (added in the previous step) belonging to this config set
- define a unique name for the config set
- activate the checkbox "Enable bean override" if multiple beans with the same ID should be overidden by the last bean (used by the BeansConfigValidator only -> if activated then bean overriding is not treated as validation error)
- activate the checkbox "Is incomplete" if this config set does not contain all beans which are referenced by other beans defined in this config set (used by the BeansConfigValidator only -> if activated then unresolved bean references are not treated as validation errors)
- externally defined config files (as described in section "Add references to other Spring projects") are decorated with a small blue arrow)

use the buttons "Move Up" and "Move Down" to change the order of the config files within the config set (important for bean overriding)

Open Spring BeansView ¶

select from within any of the added Spring BeansConfig files opened in an Eclipse editor the menu item "Navigate/Show In/Spring Beans"

once the menu item is selected the Spring BeansView is opened and the corresponding Spring BeansConfig file is selected in the view's model

double-clicking on certain entries in the Spring BeansView (bean, property or constructor argument) navigates to the corresponding location in the config file
by selecting the corresponding toolbar actions the BeansView supports alphabetical sorting and syncing with the BeansXmlEditor

Validate Spring BeansConfig file ¶

after modifying and saving any of the added Spring BeansConfig files from within an open Eclipse editor this config is automatically validated by Spring IDE
for any error occured during validation a problem marker is created and listed in Eclipse's problem view

Open Spring BeansGraph ¶

right-clicking on certain entries in the Spring BeansView (config, config set or bean) opens a read-only editor showing a graph with all beans referenced by the selected view entry

Search for Spring Beans ¶

open the search dialog via the "Search / Search..." menu
select the tab "Spring Beans Search" to switch to the BeansSearch dialog

Args4J (Java 命��o行参数控制开源项�? 使用指南

冰雨 — Wed, 12 Apr 2006 06:27:00 GMT

Args4J 使用指南

Args4J 是一个用来出来命令行的工�?

在实际的��目中用到命令行的�ƈ不是很常�?但当真正使用到时,特别是在�E�序启动旉��|�一下参数的时候就很有用了,如果参数很多的话,一个一个解析命令行�q�是比较�ȝ��?�q�时使用Args4J��q��当好办了. 在本文中我们来看看Args4J的��?当需要时能提供一个解��x��?

Args4J使用一个被�U�CؓOption�cȝ��c�L��保存输入的参�?让后�Ҏ��该类来应用参�?每个参数可以对应一个类中的属�?该属性用Annotation注释,在Annotation中给��参数的选项, �q�可以配�|�其他有用的信息.该Annotation��是 Option 注解: 该注解的doc如下:

Marks a field/setter that receives a command line switch value.

This annotation can be placed on a field of type T or the method of the form void methodName(T value). Its access modified can be anything, but if it's not public, your application needs to run in a security context that allows args4j to access the field/method (see AccessibleObject.setAccessible(boolean).

The behavior of the annotation differs depending on T --- the type of the field or the parameter of the method.

Boolean Switch

When T is boolean , it represents a boolean option that takes the form of "-OPT". When this option is set, the property will be set to true.

String Switch

When T is String, it represents an option that takes one operand. The value of the operand is set to the property.

Enum Switch

When T is derived from Enum, it represents an option that takes an operand, which must be one of the enum constant. The comparion between the operand and the enum constant name is done in a case insensitive fashion.

For example, the following definition will represent command line options like "-coin penny" or "-coin DIME" but things like "-coin" or "-coin abc" are errors.

 enum Coin { PENNY,NICKEL,DIME,QUARTER }

 class Option {
   @Option(name="-coin")
   public Coin coin;
 }

File Switch

When T is a File, it represents an option that takes a file/directory name as an operand.

该注解有5各域其中name是必��ȝ��,其他四个是可选的.如下所�C?关于该注解的详细Doc��h��?其docs.

Required Element Summary
`String`	`name` Name of the option, such as "-foo" or "-bar".

Optional Element Summary
`ClassOptionHandler>`	`handler` Specify the `OptionHandler` that processes the command line arguments.
`String`	`metaVar` When the option takes an operand, the usage screen will show something like this:
`boolean`	`required` Specify that the option is mandatory.
`String`	`usage` Help string used to display the usage screen.

当命令行讑֮��?其��用方式和java 命��o里面的参��C��用方式一�?�?java -cp ./calssPath/.......

下面通过一个例子来解释:

当不使用命��o行时�?输入信息如下:

Option "-re" is required

java SampleMain [options...] arguments...

-custom : boolean value for checking the custom handler

-n N : repeat times

rrrrrrrrrrry long

-o OUTPUT : output to this file

-re : recursively run something

��试!!!!!

Example: java SampleMain -custom -n N -o OUTPUT -re

// 注意该处没有 -str的出�?/b>/n 2.........
2 Example2: java SampleMain -re
// 注意该处没有 -str的出�?/b>
当��?-re 为命令行输入�?输出如下:// 后�ؓ作者加的注�?不是输出
Option "-str" is required
//也要指定-str该参�?
java SampleMain [options...] arguments...
-custom : boolean value for checking the custom handler
-n N : repeat times
usage can have new lines in it and also it can be verrrrrrr

当��?re -str some 为命令行输入�?�l�果如下:�q�是�׃��?3 行的判断引�v�?/p>
No argument is given
java SampleMain [options...] arguments...

2 Example2: java SampleMain -re
使用-custom -n 2 -re -str some otherstring 为命令行输入时的 �l�果如下:
. // file
-r flag is set
-custom flag is set
-str was some
-n was 2
other arguments are:
otherstring
当��?custom -n 2 -re -str some -o log.txt otherstring 时候的输出如下:
log.txt
-r flag is set
-custom flag is set
-str was some
-n was 2
other arguments are:
otherstring
当��用一个不存在的参数时�?会有Exception�?例如:-custom -ee 2 -re -str some -o log.txt otherstring

其中-ee参数不存�?�l�果如下:
"-ee" is not a valid option
java SampleMain [options...] arguments...
-custom : boolean value for checking the custom handler
-n N : repeat times
......
�׃��上的实例可以看出 args4J 取得命��o行的输入参数,然后�Ҏ��保存参数的类中的属性类型比�?br />
�q��{换�ؓ适当的�? 然后我们可以使用�q�些属性了,�q�样��免��M��自己判断args 的麻烦了,

当默认的Handler不满��你的要求时可以自己扩展Handler实现,关于�q�点请参考Args4J的测试用�?
