Spring-boot整合mybatis-plus

pom文件需要添加的依赖:

  
        com.baomidou 
        mybatis-plus-boot-starter
        2.3 
    
   
   
      org.apache.velocity 
      velocity-engine-core 
      2.0 
   

xml文件放在了resource根目录下
application.properties配置文件添加xml和实体类扫描:

mybatis-plus.mapper-locations=classpath:/mybatis/*.xml 
mybatis-plus.typeAliasesPackage=cn.com.polycis.entity 
//数据库字段下划线转驼峰 
mybatis-plus.configuration.map-underscore-to-camel-case=true

MybatisPlusConfig配置文件:

import com.baomidou.mybatisplus.plugins.PaginationInterceptor; 
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration; 
@Configuration 
//扫描dao或者是Mapper接口
@MapperScan("cn.com.polycis.mapper*") 
public class MybatisPlusConfig { 
       /** * mybatis-plus 分页插件 */ 
      @Bean 
      public PaginationInterceptor paginationInterceptor() { 
            PaginationInterceptor page = new PaginationInterceptor(); 
            page.setLocalPage(true);
           // 开启 PageHelper 的支持
           page.setDialectType("mysql"); 
           return page;
       } 
  } 

启动类需要添加mapper扫描注解:

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.SpringBootApplication; 
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration; 
import org.springframework.context.annotation.PropertySource; 
@PropertySource("application.properties") 
@MapperScan("cn.com.polycis.mapper") 
@SpringBootApplication(exclude={DataSourceAutoConfiguration.class}) 
public class OtaApplication { 
         public static void main(String[] args) {
                  SpringApplication.run(OtaApplication.class, args);
        } 
 }

至此mybatis-plus整合完成
