SpringBoot1.5.18 Cacheable不起作用，为什么，求解

Question

代码：

@Service
public class EmployeeService {

    @Autowired
    EmployeeMapper employeeMapper;

 @Cacheable(cacheNames = {"emp"})
    public  Employee getEmp(Integer id){

        System.out.println("查询"+id+"号员工");
        return employeeMapper.getEmployee(id);
    }

配置：

spring.datasource.url=jdbc:mysql://localhost:3306/spring_cache
spring.datasource.username=xxx
spring.datasource.password=xsg5207896
#spring.datasource.driver-class-name=com.mysql.jdbc.Driver
#        开启驼峰命名规则
mybatis.configuration.map-underscore-to-camel-case=true

logging.level.com.example.sbcache.mapper=debug

我看别人都是这么写的，为什么我的都不得行呢 求解 工具idea
