IDEA SpringBoot Mybatis逆向工程

IDEA SpringBoot Mybatis逆向工程

1. 添加依赖

           
           <dependency>
               <groupId>org.mybatis.spring.bootgroupId>
               <artifactId>mybatis-spring-boot-starterartifactId>
               <version>1.3.2version>
           dependency>
   
   		
           <dependency>
               <groupId>org.mybatis.generatorgroupId>
               <artifactId>mybatis-generator-coreartifactId>
               <version>1.3.6version>
           dependency>
   

2. 添加插件

       <build>
           <plugins>
               <plugin>
                   <groupId>org.springframework.bootgroupId>
                   <artifactId>spring-boot-maven-pluginartifactId>
               plugin>
               
               <plugin>
                   <groupId>org.mybatis.generatorgroupId>
                   <artifactId>mybatis-generator-maven-pluginartifactId>
                   <version>1.3.6version>
                   <dependencies>
                   
                       <dependency>
                           <groupId>mysqlgroupId>
                           <artifactId>mysql-connector-javaartifactId>
                           
                           <version>8.0.13version>
                       dependency>
                   dependencies>
               plugin>
           plugins>
       build>
   

3. 在src/main/resources下添加generatorConfig.xml文件, 内容如下:

   
   
   
   <generatorConfiguration>
       
       
       
       
       
       <context id="mybatisGenerator" targetRuntime="MyBatis3">
           <commentGenerator>
               
               <property name="suppressAllComments" value="true" />
           commentGenerator>
           
           <jdbcConnection driverClass="com.mysql.cj.jdbc.Driver"
                           connectionURL="jdbc:mysql://localhost:3306/shiro_csdn_demo?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8"
                           userId="root"
                           password="871403165">
           jdbcConnection>
   
           
           <javaTypeResolver>
               <property name="forceBigDecimals" value="false" />
           javaTypeResolver>
   
           
           <javaModelGenerator targetPackage="com.sqt.generator.bean"
                               targetProject="src/main/java">
               
               <property name="enableSubPackages" value="false" />
               
               <property name="trimStrings" value="true" />
           javaModelGenerator>
           
           <sqlMapGenerator targetPackage="mapper"
                            targetProject="src/main/resources">
               
               <property name="enableSubPackages" value="false" />
           sqlMapGenerator>
           
           <javaClientGenerator type="XMLMAPPER"
                                targetPackage="com.sqt.generator.mapper"
                                targetProject="src/main/java">
               
               <property name="enableSubPackages" value="false" />
           javaClientGenerator>
           
           <table tableName="sys_permission">table>
           <table tableName="user_info">table>
           <table tableName="sys_role">table>
           <table tableName="sys_role_permission">table>
           <table tableName="sys_user_role">table>
   
           
       context>
   generatorConfiguration>
   

   注意字节在xml中写&,会因为未转义而报错要将&写成& amp;

    connectionURL="jdbc:mysql://localhost:3306/shiro_csdn_demo?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8"
   

4. 使用插件生成代码

5. 如果使用的是java类而不是plugin来生成代码需要添加依赖, 但是可以将build中的plugin删除掉

<dependency>
      <groupId>mysqlgroupId>
    <artifactId>mysql-connector-javaartifactId>
       <version>8.0.16version>
dependency>

在java包中添加java代码, 执行该代码可以生成, 达到plugin同样的效果

public class Generator {
    public void generator() throws Exception{
        List<String> warnings = new ArrayList<String>();
        boolean overwrite = true;
        /**指向逆向工程配置文件*/
        File configFile = new File("src/main/resources/generatorConfig.xml");
        ConfigurationParser parser = new ConfigurationParser(warnings);
        Configuration config = parser.parseConfiguration(configFile);
        DefaultShellCallback callback = new DefaultShellCallback(overwrite);
        MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config,
                callback, warnings);
        myBatisGenerator.generate(null);
    }
    public static void main(String[] args) throws Exception {
        try {
            Generator generatorSqlmap = new Generator();
            generatorSqlmap.generator();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
