修改war包中数据库配置信息

### 第一步：war -> jar ###

1、将war包解压缩

2、创建目录，层级与.java文件包名一致，把.class文件移到该目录下(如果路径名与包名不一致，转dex操作会报错)

3、用jdk/bin目录下的jar命令， jar cvf 生成.jar class目录或class文件,得到jar文件

### 第二步：class -> dex ###

需要工具：

Android Build-Tools&SDK tools

**需要将下载好的build-tools解压放到adroid-sdk-windows文件夹下**

4、用Android sdk/build-tools下的命令dx --dex --output=destFile\_dex.jar destFile.jar得到包含.dex类型的jar包

5、把后缀jar改为zip进行解压后取得class.dex文件

### 第三步：dex -> smali ###

工具：baksmali

下载地址：

6、运行jar包 baksmali disassemble classes.dex -o 输出路径 ， 得到包含smali文件的文件夹

### 第四步：修改smali中的数据库信息 ###

### 第五步：smali -> dex ###

工具：smali

下载地址：[https://bitbucket.org/JesusFreke/smali/downloads/][https_bitbucket.org_JesusFreke_smali_downloads]

git项目地址：[https://github.com/JesusFreke/smali][https_github.com_JesusFreke_smali]

7、运行jar包 smali assemble smali文件夹 -o classes.dex ， 得到classes.dex文件

### 第六步：dex -> class ###

工具：dex2jar

下载地址：[https://sourceforge.net/projects/dex2jar/][https_sourceforge.net_projects_dex2jar]

8、使用命令d2j-dex2jar.bat  classes.dex得到修改后的jar包

### 第七步：修改后缀为zip解压出来，使用jd-gui查看修改结果 ###

工具：jd-gui

下载地址：[http://java-decompiler.github.io/][http_java-decompiler.github.io]

将class文件拖入jd-gui查看
