SpringBoot_ integrated MyBatis

Spring boot step integrated MyBatis follows:

1, the configuration dependent correlation jar in pom.xml

<! - Load mybatis integration springboot ->
<dependency>
   <groupId>org.mybatis.spring.boot</groupId>
   <artifactId>mybatis-spring-boot-starter</artifactId>
   <version>1.3.1</version>
</dependency>

<-! MySQL's jdbc driver package ->
<dependency>
   <groupId>mysql</groupId>
   <artifactId>mysql-connector-java</artifactId>
</dependency>

2, the configuration in the core MyBatis configuration file application.properties Springboot in Mapper.xml file location:

# MyBatis configuration file is located in the Mapper.xml
mybatis.mapper-locations=classpath:com/example/springboot01/mapper/*.xml

3, the configuration data in the configuration file source application.properties core Springboot of:

# Configure Data Source
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/exam?useUnicode=true&characterEncoding=utf8&useSSL=false

4, the new dao interfaces, add annotations Mapper @Mapper MyBatis in the interface or add @MapperScan ( "com.bjpowernode.springboot.mapper") running on the main scanning type package of annotations

@Mapper
 public  interface TClassMapper {
    List<TClass> list();
}

or

 5, write mybatis map file, used here maven plug-in generates automatic code generation for the mybatis

 

 

New service and controller

public  interface TClassService {
    List<TClass> list();
}

@Controller
public  class HelloController {
    @Autowired
    private TClassService tClassService;

    @RequestMapping("index.do")
    public @ResponseBody Object list(){

        Return tClassService.list ();
    }

}

If the service being given the injection, the tool is a problem, it can change warning
