若依后端MyBatis改为MyBatis-Plus方式

java 来源：互联网 作者：佚名 发布时间：2024-11-16 10:48:22 人浏览
摘要

1.引入MyBatis-Plus依赖 在总目录的pom.xml，导入依赖 1 2 3 4 5 6 7 8 mybatis-plus.version3.4.3/mybatis-plus.version !-- mybatis-plus 增强CRUD -- dependency groupIdcom.baomidou/groupId artifactIdmybatis-plus-boot-starter/artifactId versi

1.引入MyBatis-Plus依赖

在总目录的pom.xml，导入依赖

<mybatis-plus.version>3.4.3</mybatis-plus.version>

 

<!-- mybatis-plus 增强CRUD -->

<dependency>

<groupId>com.baomidou</groupId>

<artifactId>mybatis-plus-boot-starter</artifactId>

<version>${mybatis-plus.version}</version>

</dependency>

2.在ruoyi-common下的pom.xml添加mybatis-plus依赖

<!-- mybatis-plus 增强CRUD -->

<dependency>

    <groupId>com.baomidou</groupId>

    <artifactId>mybatis-plus-boot-starter</artifactId>

</dependency>

3.修改配置文件

ruoyi-admin下src\main\resources\application.yml,注释mybatis的配置，新增plus的配置，这段配置我是从若依官方拷贝过来的，如果跟你实际不一样就修改一下

# MyBatis配置

#  # 搜索指定包别名

#  typeAliasesPackage: com.spiceIngredients.**.domain

#  # 配置mapper的扫描，找到所有的mapper.xml映射文件

#  mapperLocations: classpath*:mapper/**/*Mapper.xml

#  # 加载全局的配置文件

#  configLocation: classpath:mybatis/mybatis-config.xml

# MyBatis Plus配置

mybatis-plus:

  # 搜索指定包别名

  typeAliasesPackage: com.spiceIngredients.**.domain

  # 配置mapper的扫描，找到所有的mapper.xml映射文件

  mapperLocations: classpath*:mapper/**/*Mapper.xml

  # 加载全局的配置文件

  configLocation: classpath:mybatis/mybatis-config.xml

  # MyBatis-Plus分页插件配置

  pagination:

    # 分页合理化参数，默认false

    reasonable: true

    # 支持通过 Mapper 接口参数来传递分页参数

    supportMethodsArguments: true

    # 默认值为false，设置为true时，允许在参数中使用countSql

    params: count=countSql

4.重写mybatis配置文件

在framework中，找到MybatisConfig文件，然后删除，在刚删除的文件夹下，新建一个MybatisPlus的java文件，复制已下内容到java文件中：

@EnableTransactionManagement(proxyTargetClass = true)

@Configuration

public class MybatisPlusConfig

{

    @Bean

    public MybatisPlusInterceptor mybatisPlusInterceptor()

    {

        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();

        // 分页插件

        interceptor.addInnerInterceptor(paginationInnerInterceptor());

        // 乐观锁插件

        interceptor.addInnerInterceptor(optimisticLockerInnerInterceptor());

        // 阻断插件

        interceptor.addInnerInterceptor(blockAttackInnerInterceptor());

        return interceptor;

    }

 

    /**

     * 分页插件，自动识别数据库类型 https://baomidou.com/guide/interceptor-pagination.html

     */

    public PaginationInnerInterceptor paginationInnerInterceptor()

    {

        PaginationInnerInterceptor paginationInnerInterceptor = new PaginationInnerInterceptor();

        // 设置数据库类型为mysql

        paginationInnerInterceptor.setDbType(DbType.MYSQL);

        // 设置最大单页限制数量，默认 500 条，-1 不受限制

        paginationInnerInterceptor.setMaxLimit(-1L);

        return paginationInnerInterceptor;

    }

 

    /**

     * 乐观锁插件 https://baomidou.com/guide/interceptor-optimistic-locker.html

     */

    public OptimisticLockerInnerInterceptor optimisticLockerInnerInterceptor()

    {

        return new OptimisticLockerInnerInterceptor();

    }

 

    /**

     * 如果是对全表的删除或更新操作，就会终止该操作 https://baomidou.com/guide/interceptor-block-attack.html

     */

    public BlockAttackInnerInterceptor blockAttackInnerInterceptor()

    {

        return new BlockAttackInnerInterceptor();

    }

}

5.把代码生成修改为mybatis-plus版本

ruoyi-generator下src\main\resources\vm\java 文件夹下面，直接文件内容替换：
