慢慢看《Hadoop實戰中文版》，了解分布式系統
認真閱讀《設計模式之禪》，加深對自己已經在實際項目中運用的模式的理解。
閱讀《java解惑》的后半部分（2年前讀過前幾十條建議），了解編碼中的陷阱。

【轉】java進制轉換

十進制轉成十六進制：
Integer.toHexString(int i)
十進制轉成八進制
Integer.toOctalString(int i)
十進制轉成二進制
Integer.toBinaryString(int i)
十六進制轉成十進制
Integer.valueOf("FFFF",16).toString()
八進制轉成十進制
Integer.valueOf("876",8).toString()
二進制轉十進制
Integer.valueOf("0101",2).toString()

有什么方法可以直接將2,8,16進制直接轉換為10進制的嗎?
java.lang.Integer類
parseInt(String s, int radix)
使用第二個參數指定的基數，將字符串參數解析為有符號的整數。
examples from jdk:
parseInt("0", 10) returns 0
parseInt("473", 10) returns 473
parseInt("-0", 10) returns 0
parseInt("-FF", 16) returns -255
parseInt("1100110", 2) returns 102
parseInt("2147483647", 10) returns 2147483647
parseInt("-2147483648", 10) returns -2147483648
parseInt("2147483648", 10) throws a NumberFormatException
parseInt("99",

throws a NumberFormatException
parseInt("Kona", 10) throws a NumberFormatException
parseInt("Kona", 27) returns 411787

進制轉換如何寫（二，八，十六）不用算法
Integer.toBinaryString
Integer.toOctalString
Integer.toHexString

例二

public class Test{
   public static void main(String args[]){

    int i=100;
    String binStr=Integer.toBinaryString(i);
    String otcStr=Integer.toOctalString(i);
    String hexStr=Integer.toHexString(i);
    System.out.println(binStr);

}

例二
public class TestStringFormat {
   public static void main(String[] args) {
    if (args.length == 0) {
       System.out.println("usage: java TestStringFormat <a number>");
       System.exit(0);
    }

    Integer factor = Integer.valueOf(args[0]);

    String s;

    s = String.format("%d", factor);
    System.out.println(s);
    s = String.format("%x", factor);
    System.out.println(s);
    s = String.format("%o", factor);
    System.out.println(s);
   }
}

其他方法：

Integer.toHexString(你的10進制數);
例如
String temp = Integer.toHexString(75);
輸出temp就為 4b

//輸入一個10進制數字并把它轉換成16進制
import java.io.*;
public class toHex{

public static void main(String[]args){

int input;//存放輸入數據
//創建輸入字符串的實例
BufferedReader strin=new BufferedReader(new InputStreamReader(System.in));
System.out.println("請輸入一個的整數：");
String x=null;
try{
x=strin.readLine();
}catch(IOException ex){
ex.printStackTrace();
}
input=Integer.parseInt(x);
System.out.println ("你輸入的數字是："+input);//輸出從鍵盤接收到的數字

System.out.println ("它的16進制是："+Integer.toHexString(input));//用toHexString把10進制轉換成16進制

javassist.NotFoundException

Class search path

The default ClassPool returned by a static method ClassPool.getDefault() searches the same path that the underlying JVM (Java virtual machine) has. If a program is running on a web application server such as JBoss and Tomcat, the ClassPool object may not be able to find user classes since such a web application server uses multiple class loaders as well as the system class loader. In that case, an additional class path must be registered to the ClassPool. Suppose that pool refers to aClassPool object:

pool.insertClassPath(new ClassClassPath(this.getClass()));

This statement registers the class path that was used for loading the class of the object that this refers to. You can use any Class object as an argument instead ofthis.getClass(). The class path used for loading the class represented by that Class object is registered.

You can register a directory name as the class search path. For example, the following code adds a directory /usr/local/javalib to the search path:

ClassPool pool = ClassPool.getDefault(); pool.insertClassPath("/usr/local/javalib");

The search path that the users can add is not only a directory but also a URL:

ClassPool pool = ClassPool.getDefault(); ClassPath cp = new URLClassPath("www.javassist.org", 80, "/java/", "org.javassist."); pool.insertClassPath(cp);

This program adds "http://www.javassist.org:80/java/" to the class search path. This URL is used only for searching classes belonging to a package org.javassist. For example, to load a class org.javassist.test.Main, its class file will be obtained from:

http://www.javassist.org:80/java/org/javassist/test/Main.class

Furthermore, you can directly give a byte array to a ClassPool object and construct a CtClass object from that array. To do this, use ByteArrayClassPath. For example,

ClassPool cp = ClassPool.getDefault(); byte[] b = a byte array; String name = class name; cp.insertClassPath(new ByteArrayClassPath(name, b)); CtClass cc = cp.get(name);

The obtained CtClass object represents a class defined by the class file specified by b. The ClassPool reads a class file from the given ByteArrayClassPath if get() is called and the class name given to get() is equal to one specified by name.

If you do not know the fully-qualified name of the class, then you can use makeClass() in ClassPool:

ClassPool cp = ClassPool.getDefault(); InputStream ins = an input stream for reading a class file; CtClass cc = cp.makeClass(ins);

makeClass() returns the CtClass object constructed from the given input stream. You can use makeClass() for eagerly feeding class files to the ClassPool object. This might improve performance if the search path includes a large jar file. Since a ClassPool object reads a class file on demand, it might repeatedly search the whole jar file for every class file. makeClass() can be used for optimizing this search. The CtClass constructed by makeClass() is kept in the ClassPool object and the class file is never read again.

The users can extend the class search path. They can define a new class implementing ClassPath interface and give an instance of that class to insertClassPath() inClassPool. This allows a non-standard resource to be included in the search path.

默認的內置攔截器

anon(AnonymousFilter.class),

authc(FormAuthenticationFilter.class),

authcBasic(BasicHttpAuthenticationFilter.class),

logout(LogoutFilter.class),

noSessionCreation(NoSessionCreationFilter.class),

roles(RolesAuthorizationFilter.class),

ssl(SslFilter.class),

user(UserFilter.class);

anno 允許匿名訪問，

Filter that allows access to a path immeidately without performing security checks of any kind.

This filter is useful primarily in exclusionary policies, where you have defined a url pattern to require a certain security level, but maybe only subset of urls in that pattern should allow any access.

For example, if you had a user-only section of a website, you might want to require that access to any url in that section must be from an authenticated user.

Here is how that would look in the IniShiroFilter configuration:

[urls] /user/** = authc

But if you wanted /user/signup/** to be available to anyone, you have to exclude that path since it is a subset of the first. This is where the AnonymousFilter ('anon') is useful:

[urls] /user/signup/** = anon /user/** = authc>

Since the url pattern definitions follow a 'first match wins' paradigm, the anon filter will match the /user/signup/** paths and the /user/** path chain will not be evaluated.

JVM concurrent mode failure

項目運行了一段時間后大量concurrent mode failure （gc 日志文件下載/Files/b1412/concurrent_mode_failure.rar）

參數

SET CATALINA_OPTS= -Xms1024m -Xmx1024m -Xmn350m -server -noclassgc -XX:+PrintGCDetails -XX:ParallelGCThreads=4 -XX:MaxTenuringThreshold=20 -XX:+UseConcMarkSweepGC -XX:+CMSParallelRemarkEnabled -XX:CMSInitiatingOccupancyFraction=80 -XX:+UseFastAccessorMethods -Xloggc:"%CATALINA_HOME%"/webapps/dm/tomcat_gc.log

XX:CMSInitiatingOccupancyFraction 參數默認值是68，之前調試的時候為了降低cms gc觸發周期，擴大了這個值，也就是old達到百分之80才觸發cms。但是長期運行隨著old區的膨脹，開始頻繁觸發concurrent mode failure 。具體原因可以查閱相關資料，降低整個值可以避免，concurrent mode failure觸發會暫停整個應用大大影響效率。

讀書計劃

1重構改善既有代碼的設計
大概看了不少了也實踐了一些。主要是方法抽取的一些重構。感覺到現在來說做的項目什么設計啊都亂七八糟的，什么面向對象設計的，關系也都亂七八糟，總體來說我也是比較實用主義者，有些理論也只有一定情況才能試用，不過重構的話方法抽取啊這些還是很有用的，把方法寫的和注釋一樣，讀代碼就和讀注釋差不多，那么目前把這些重構原則用好也差不多了

2Head_First
設計模式的比較出名的書籍，場景將的很細致了，還是那句話，目前的項目都沒有那么嚴格和大規模的設計，不過很多小的模塊自己能用一些簡單的設計模式也不錯，就算沒有真正需要擴展和一些性能的要求，提高了代碼可讀性也算不錯了了。單例，工廠這些就不多說了，太普遍。現在享元也用了下，這次做自定義協議實現時候用的xml和命令對象的轉換參照了commons beanutils 中convertUtils類型轉換的設計，后來看了這書發現有點類似的命令模式。對于模式各方褒貶不一，我理解現在我這個階段寫代碼能基本復用易讀差不多了，能參考一些模式的思想吧代碼結構優化好就行，模式不是用來生搬硬套的教條，只要你這個代碼結構能應對這個系統的需求變化就行。

3Java敏捷開發
看這本主要還是看一些重構和提高代碼可讀性的一些東西，變量方法命令等等。

最后之所以這個讀書計劃沒有時間，主要是我覺得看書是為了更好的再工作中實踐，提高質量。用到什么了需要了就在這些里面去找方案，而不是要一口氣把書看完，那么也沒有太大的價值
