今天新建springboot工程测试的时候,请求一直访问不到,抛出异常: Whitelabel Error Page This application has no explicit mapping for /error, so you are seeing this as a fallback.
Sat Jul 04 21:06:06 CST 2020 There was an unexpected error (type=Not Found, status=404)…; 如下图: 解决方式: 将@Service换成@Controller即可;
原代码(有问题的代码):
@Service
public class Busi002ServiceImpl implements IBusi002Service {
@ResponseBody
@RequestMapping("/hello")
public String
test() {
return "Hello World!";
}
}
修改过后的代码:
@Controller
public class Busi002ServiceImpl implements IBusi002Service {
@ResponseBody
@RequestMapping("/hello")
public String
test() {
return "Hello World!";
}
}
修改后的效果:
至于@Controller和@Service的具体区别还没有搞明白,不知道为什么有的项目可以使用@Service,应该是做过什么处理吧。
