在 maven项目下.mybatis 自动生成xml

pom.xml

1. 要使用generator插件自动生成相关文件，需要引入mybatis-generator-core这个包，在<dependencys>中加入：

<dependency>
    
            <groupId>org.mybatis.generator</groupId>
    
         <artifactId>mybatis-generator-core</artifactId>
    
            <version>1.3.5</version>
    
          </dependency>

2.在 <build> 这个节点的<plugins>节点内部加入一个<plugin>，如下：

<plugin>
    
               <groupId>org.mybatis.generator</groupId>
    
               <artifactId>mybatis-generator-maven-plugin</artifactId>
    
               <version>1.3.2</version>
    
               <executions>
    
                  <execution>
    
                     <id>Generate MyBatis Files</id>
    
                     <goals>
    
                        <goal>generate</goal>
    
                     </goals>
    
                     <phase>generate</phase>
    
                     <configuration>
    
                        <verbose>true</verbose>
    
                        <overwrite>true</overwrite>
    
                     </configuration>
    
                  </execution>
    
               </executions>
    
    
    
               <dependencies>
    
                  <dependency>
    
                     <groupId>mysql</groupId>
    
                     <artifactId>mysql-connector-java</artifactId>
    
                     <version>5.1.38</version>
    
                  </dependency>
    
                  <dependency>
    
                     <groupId>org.mybatis.generator</groupId>
    
               <artifactId>mybatis-generator-core</artifactId>
    
                     <version>1.3.5</version>
    
                  </dependency>
    
    
    
                  <dependency>
    
                     <groupId>org.mybatis</groupId>
    
                     <artifactId>mybatis</artifactId>
    
                     <version>3.4.2</version>
    
                  </dependency>
    
               </dependencies>
    
            </plugin>

3. 在resource目录下创建generatorConfig.xml配置文件，当然了该文件起这个名字，并且放到resource根目录下是根据genereator的默认方案来的，如果要用别的名，放到别的目录也可以，只是要做其它配置，这里就按默认算了，该文件的配置内容如下：

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
    <generatorConfiguration>
    
    <context id="mysqlTables" targetRuntime="MyBatis3">
    
    <property name="javaFileEncoding" value="UTF-8"/>
    
    <property name="javaFormatter" value="org.mybatis.generator.api.dom.DefaultJavaFormatter"/>
    
    <property name="xmlFormatter" value="org.mybatis.generator.api.dom.DefaultXmlFormatter"/>
    
    
    <commentGenerator>
    <property name="suppressAllComments" value="true" />
    </commentGenerator>
    
    
    <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://127.0.0.1:3306/lawsuit" userId="root" password="ROOT">
    </jdbcConnection>
    <javaTypeResolver>
    <property name="forceBigDecimals" value="false" />
    </javaTypeResolver>
    
    <javaModelGenerator targetPackage="com.justitia.domain.entity.caseauth" targetProject="src/main/java">
    <property name="enableSubPackages" value="true" />
    <property name="trimStrings" value="true" />
    </javaModelGenerator>
    
    <sqlMapGenerator targetPackage="mybatis.mapper.caseauth" targetProject="src/main/resources">
    <property name="enableSubPackages" value="true" />
    </sqlMapGenerator>
    
    <javaClientGenerator type="XMLMAPPER" targetPackage="com.justitia.dao.caseauth" targetProject="src/main/java">
    <property name="enableSubPackages" value="true" />
    </javaClientGenerator>
    
    
    
    
    <table tableName="test_user" domainObjectName="TestUser" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />
    
    </context>
    </generatorConfiguration>

# 4.对项目做运行参数配置并执行命令 #

在新出现的界面上填写Name，Base directory，Goals这三个地方，其中Name可以随便写，Base directory是你的工程的路径，例如我的是E:\\eclipse\_workspace\_2015\\springmybatis，Goals这个地方不用变，照着图写，这个是maven插件的命令。至于Maven Runtime下拉框可以不选，也可以选择自己安装在eclipse外面的那个。

## 5.执行mybatis-generator:generate命令 ##

6.在entity目录下生成了对应的实体.java文件，如图：
