SSM生成逆向工程

Posted 2021-03-24 book3

1.pom.xml将pom中的build替换成一下代码

<build>
    <plugins>
      <plugin>
        <groupId>org.mybatis.generator</groupId>
        <artifactId>mybatis-generator-maven-plugin</artifactId>
        <version>1.3.7</version>
        <configuration>
          <verbose>true</verbose>
          <overwrite>true</overwrite>
        </configuration>
        <dependencies><dependency>
          <groupId>mysql</groupId>
          <artifactId>mysql-connector-java</artifactId>
          <version>5.1.38</version>
        </dependency></dependencies>
      </plugin>
    </plugins>
  </build>

2.在resources包里加入generatorConfig.xml,注意将

targetProject=".srcmainjava的对应路径名进行更改

<?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>
    <!-- 
        无Example等内容-->
        <context id="Mysql" targetRuntime="MyBatis3Simple" defaultModelType="flat">    
     
     
     <!-- 有Example查询条件内容 -->
    <!-- <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="com.mysql.jdbc.Driver"
            connectionURL="jdbc:mysql://localhost:3306/home5"
            userId="root"
            password="xxxxxx">
        </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Entity类的路径 -->
        <javaModelGenerator targetProject=".srcmainjava" targetPackage="entity">
            <!-- 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:XXXMapper.xml映射文件生成的路径 -->
        <sqlMapGenerator targetProject=".srcmain
esources" targetPackage="mapper">
            <!-- 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" targetProject=".srcmainjava" targetPackage="mapper">
            <!-- enableSubPackages:是否让schema作为包的后缀 -->
            <property name="enableSubPackages" value="false" />
        </javaClientGenerator>
            <!--把库中的所有表创建成同名的类-->
            <table tableName="%" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false"
                   enableSelectByExample="false" selectByExampleQueryId="false" >
            </table>
</context>
</generatorConfiguration>
