添加依赖
添加统一处理依赖
<dependency>
<groupId>io.gitee.javalaoniu</groupId>
<artifactId>jud-springboot-starter</artifactId>
<version>0.0.1</version>
</dependency>
启用统一处理
添加 @EnableUnifiedDisposal 注解
import io.gitee.javalaoniu.jud.annotation.EnableUnifiedDisposal;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@EnableUnifiedDisposal
@SpringBootApplication
public class JudDemoApplication {
public static void main(String[] args {
SpringApplication.run(JudDemoApplication.class, args;
}
}
拦截的处理
像平常一样返回数据即可，不需要做其它

}
@IgnoreResponseAdvice
@GetMapping("test9"
public String ignoreResponseTest( {
return "IgnoreResponseAdvice";
// IgnoreResponseAdvice
}
@GetMapping("test10"
public String businessExceptionTest( {
throw new BusinessException(ExceptionCode.EXCEPTION;
// {"succ":false,"ts":1673943862588,"data":null,"code":500,"msg":"服务器开小差，请稍后再试(Internal Server Error"}
}
}
不拦截处理
对不需要统一处理的controller或者方法使用下面注解
@IgnoreResponseAdvice
@GetMapping("test9"
public String ignoreResponseTest( {
// 在方法上使用，直接返回IgnoreResponseAdvice字符串给前端
return "IgnoreResponseAdvice";
}
可以看到，使用统一处理starter后，统一返回对象和统一异常处理不需要自己在处理，非常方便。
