spring项目启动执行

在非springboot的spring项目中要实现在项目启动后执行某个操作且在spring的bean生命周期内，可以通过实现InitializingBean

@Component
public class InitDataListener implements InitializingBean {

    @Autowired
    TestMapper testMapper;

    @Autowired
    TestService testService;

    @Override
    public void afterPropertiesSet() throws Exception {
        System.out.println("===========");
        List<Test> tests = testMapper.findAll();
        System.out.println(tests);
        System.out.println("===========");
        System.out.println(testService.findAllTests());
    }
}

　　启动后的结果：
