generate插件 在SpringBoot项目中利用maven的generate插件
staHuri 人气:0使用maven 插件 generate生成MyBatis相关文件
在项目中增加 maven 依赖
- - mybatis-spring-boot-starter
- - mysql-connector-java
- - mybatis-generator-maven-plugin 插件 自动读取 resources 下的generatorConfig.xml 文件

SpringBoot 项目中application.properties 配置
- mybatis.mapper-locations 用来指定mapper 存放路径
- spring.datasource.username 用来指定 用户名
- spring.datasource.password 用来指定密码
- spring.datasource.driver-class-name 用来指定链接驱动
- spring.datasource.url 用来指定链接路由地址
mybatis.mapper-locations=classpath:com/wangspringboot/demo/mapper/*.xml spring.datasource.username=root spring.datasource.password=root spring.datasource.driver-class-name=com.mysql.jdbc.Driver spring.datasource.url=jdbc:mysql://localhost:3306/wt?useUnicode=true&characterEncoding=utf8&useSSL=false
resources 下配置 generatorConfig.xml

查看插件
执行
选中maven 下 generator 双击运行
SpringBootMyBatis 使用
在 service 的实现类上添加 @Service 注解
@Service
public class TqServiceImpl implements TqService {
@Autowired
private TqMapper tqmapper;
@Override
public Tq insTq() {
Tq t = new Tq();
t.setZ(12.0);
t.setY(12.0);
t.setX(12.0);
tqmapper.insert(t);
return t;
}
}
相关调用
@RestController
public class MyBatisController {
@Autowired
private TqService tqService;
@GetMapping("/boot/tq")
public Object tq(){
return tqService.insTq();
}
}
启动SpringBoot WEB项目后 访问
{
x: 12,
y: 12,
z: 12
}
