1.添加配置文件 mybatis-config.xml <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <!--驼峰命名--> <settings> <setting name="mapUnderscoreToCamelCase" value="true"/> </settings> </configuration> EmployeeMapper.xml <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.baoxing.springboot.mapper.EmployeeMapper"> <!-- public Employee getEmpById(Integer id); public void insertEmp(Employee employee); --> <select id="getEmpById" resultType="com.baoxing.springboot.bean.Employee"> select * from employee where id=#{id} </select> <insert id="insertEmp"> INSERT INTO employee(lastName,email,gender,d_id) VALUES (#{lastName},#{email},#{gender},#{did}) </insert> </mapper>
application.yml配置文件 主要看mybatis对应的配置 spring: datasource: username: root password: root url: jdbc:mysql://localhost:3306/test driver-class-name: com.mysql.jdbc.Driver type: com.alibaba.druid.pool.DruidDataSource # schema: # - classpath:sql/department.sql # - classpath:sql/employee.sql # 数据源其他配置 initialSize: 5 minIdle: 5 maxActive: 20 maxWait: 60000 timeBetweenEvictionRunsMillis: 60000 minEvictableIdleTimeMillis: 300000 validationQuery: SELECT 1 FROM DUAL testWhileIdle: true testOnBorrow: false testOnReturn: false poolPreparedStatements: true # 配置监控统计拦截的filters,去掉后监控界面sql无法统计,‘wall‘用于防火墙 filters: stat,wall,log4j maxPoolPreparedStatementPerConnectionSize: 20 useGlobalDataSourceStat: true connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500 mybatis: config-location: classpath:mybatis/mybatis-config.xml mapper-locations: classpath:mybatis/mapper/*.xml
EmployeeMapper类 @Mapper public interface EmployeeMapper { public Employee getEmpById(Integer id); public void insertEmp(Employee employee); }
Controller类 @RestController public class DepartmentController { @Autowired private DepartmentMapper departmentMapper; @Autowired private EmployeeMapper employeeMapper; @GetMapping(value = "/dept/{id}") public Department getDepartment(@PathVariable("id") Integer id){ return departmentMapper.getDeptById(id); } @GetMapping(value = "/dept") public Department insertDept(Department department){ departmentMapper.insertDept(department); return department; } @GetMapping(value = "emp/{id}") public Employee getEmp(@PathVariable("id")Integer id){ return employeeMapper.getEmpById( id); } }
