1、检查依赖是否正确
com.baomidou
mybatis-plus-boot-starter
${mybatis-plus.version}
2、检查是否添加配置文件
MybatisPlusConfig.java
${mybatis-plus.version}=3.2.0
旧版本
@Configuration
@EnableTransactionManagement
@MapperScan( { "com.cat.coder.dao" })
public class MybatisPlusConfig {
@Bean
public PaginationInterceptor paginationInterceptor() {
return new PaginationInterceptor().setDialectType("mysql");
}
}
新版本
${mybatis-plus.version}=3.4.0
@Configuration
@EnableTransactionManagement
@MapperScan( { "com.cat.coder.dao" })
public class MybatisPlusConfig {
@Bean
public MybatisPlusInterceptor mybatisPlusInterceptor() {
MybatisPlusInterceptor mybatisPlusInterceptor = new MybatisPlusInterceptor();
mybatisPlusInterceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
return mybatisPlusInterceptor;
}
}
3、如果自定义了SqlSessionFactory（自行根据版本替换插件）
MybatisPlusConfig.java
@Configuration
@EnableTransactionManagement
@MapperScan( { "com.cat.coder.dao" })
public class MybatisPlusConfig {
@Bean(name = "session_factory")
public SqlSessionFactory sqlSessionFactory(@Qualifier("cat") DataSource dataSource) throws Exception {
// 其它代码 .....
//关键代码 设置 MyBatis-Plus 分页插件
Interceptor[] plugins = {paginationInterceptor()};
sqlSessionFactoryBean.setPlugins(plugins);
// 其它代码 .....
return sqlSessionFactoryBean.getObject();
}
@Bean
public PaginationInterceptor paginationInterceptor() {
return new PaginationInterceptor().setDialectType("mysql");
}
}
