mybatis自动生成mapper和pojo

1、在resources下新建generatorConfig.xml

<?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">

<!-- 配置Run As Maven build : Goals 参数 : mybatis-generator:generate -Dmybatis.generator.overwrite=true -->
<!-- 配置 tableName,使用 Run As Maven build 生成 dao model 层 -->
<generatorConfiguration>
    <!-- 配置文件路径 -->
    <classPathEntry location="D:/javatool/workspaces/FCSROOT/src/main/webapp/WEB-INF/lib/ojdbc6.jar" />

    <context id="testTables" targetRuntime="MyBatis3">
        <commentGenerator>
            <!-- 是否去除自动生成的注释 true：是 ： false:否 -->
            <property name="suppressAllComments" value="true" />
        </commentGenerator>
        <!--数据库连接的信息：驱动类、连接地址、用户名、密码 -->
        <jdbcConnection driverClass="oracle.jdbc.driver.OracleDriver"
                        connectionURL="jdbc:oracle:thin:@localhost:1521:ORCL" userId="c##fcs"
                        password="init1234">
        </jdbcConnection>
        <!-- 默认false，把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer，为 true时把JDBC DECIMAL 和
           NUMERIC 类型解析为java.math.BigDecimal -->
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>

        <!-- targetProject:生成PO类的位置 -->
        <javaModelGenerator targetPackage="com.ecps.seckill.pojo"
                            targetProject="src/main/java">
            <!-- enableSubPackages:是否让schema作为包的后缀 -->
            <property name="enableSubPackages" value="false" />
            <!-- 从数据库返回的值被清理前后的空格 -->
            <property name="trimStrings" value="true" />
        </javaModelGenerator>
        <!-- targetProject:mapper映射文件生成的位置
           如果maven工程只是单独的一个工程，targetProject="src/main/java"
           若果maven工程是分模块的工程，targetProject="所属模块的名称"，例如：
           targetProject="ecps-manager-mapper"，下同-->
        <sqlMapGenerator targetPackage="com.ecps.seckill.mapper"
                         targetProject="src/main/java">
            <!-- enableSubPackages:是否让schema作为包的后缀 -->
            <property name="enableSubPackages" value="false" />
        </sqlMapGenerator>
        <!-- targetPackage：mapper接口生成的位置 -->
        <javaClientGenerator type="XMLMAPPER"
                             targetPackage="com.ecps.seckill.mapper"
                             targetProject="src/main/java">
            <!-- enableSubPackages:是否让schema作为包的后缀 -->
            <property name="enableSubPackages" value="false" />
        </javaClientGenerator>
        <!-- 指定数据库表 -->
        <table schema="" tableName="TM_MBASE"></table>
        <table schema="" tableName="TM_MENU"></table>
    </context>
</generatorConfiguration>

2、在pom.xml的build中与pluginManagement同级新增plugins标签

<plugins>
      <plugin>
        <groupId>org.mybatis.generator</groupId>
        <artifactId>mybatis-generator-maven-plugin</artifactId>
        <version>1.3.2</version>
        <configuration>
          <!--配置文件的位置-->
          <configurationFile>src/main/resources/generatorConfig.xml</configurationFile>
          <verbose>true</verbose>
          <overwrite>true</overwrite>
        </configuration>
        <executions>
          <execution>
            <id>Generate MyBatis Artifacts</id>
            <goals>
              <goal>generate</goal>
            </goals>
          </execution>
        </executions>
        <dependencies>
          <dependency>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-core</artifactId>
            <version>1.3.2</version>
          </dependency>
        </dependencies>
      </plugin>
    </plugins>

3、在Idea右侧点击maven按钮会看到mybatis-generator选项，点开后选择Run Maven Build
