spring boot  約定優於配置 ，整合mybatis 時候，一般也採用mybatis 註解sql .

下面簡單介紹一下。

1：spring boot  pom 新增對mybatis 的支援及分頁外掛。

 <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>1.1.1</version>
        </dependency>
        
        
        <dependency>
<groupId>com.github.pagehelper</groupId>
<artifactId>pagehelper-spring-boot-starter</artifactId>
<version>1.1.0</version>
</dependency>


<dependency>
<groupId>com.github.abel533</groupId>
<artifactId>mapper</artifactId>
<version>3.0.0</version>
</dependency>

2： 編寫mapper

   public interface Mtper<T> {



 @InsertProvider(method = "insertSelective", type = BaseProvider.class)
   int save(T t);
   
   
   
   @UpdateProvider(method = "updateByPrimaryKeySelective", type = BaseProvider.class)
   int update(T t);
   
   
   
   @DeleteProvider(method = "deleteByPrimaryKey", type = BaseProvider.class)
   int deleteByKey(T t,Object val);
   
   
   
   @SelectProvider(type=BaseProvider.class,method = "selectByPrimaryKey")
   T selectByKey(Class<?> clazz,Object val);
   
   
   @InsertProvider(type = BaseProvider.class, method = "insertAll")  
   int insertAll(@Param("list") List<T> list,T t);  

}

3: 編寫sql 指令碼

public class UserDynaSqlProvider extends BaseProvider {


    
public String findTutorByIdSql(User user) {
return "select u.id as id,c.cards as cards   from user u LEFT JOIN  card c on u.id=c.uid and u.id="
+ user.getId();


}


}

4：在service 層注入對應的mapper,  處理好業務邏輯即可
