SpringBoot之接口鉴权

有的时候,我们要对接口进行管理,确定登录,然后就有了如下案例

继承

HandlerInterceptorAdapter抽象类进行接口鉴权

若接口不满意还可以选择如下接口

(HandlerInterceptorAdapter--->AsyncHandlerInterceptor--->HandlerInterceptor)

案例代码

启动类

import ;
import ;

@SpringBootApplication
public class Demo2Application {

    public static void main(String[] args) {
        (, args);
        ("OK.....");
    }

}

配置类

import .;
import ;
import ;
import ;

@Configuration
public class InterceptorConfig implements WebMvcConfigurer {
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        //添加路径
        (new AuthorizationInterceptor()).addPathPatterns("/test/**");
        (new AuthorizationInterceptor()).addPathPatterns("/test2/**");
        //排除路径
        (new AuthorizationInterceptor()).excludePathPatterns("/api/login");
    }
}

鉴权处理类(这里仅仅是判定UA长度进行判定,请自行替换)

import ;
import ;
import ;

import ;
import ;
import ;

@Component
public class AuthorizationInterceptor extends HandlerInterceptorAdapter {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        if (!(handler instanceof HandlerMethod)) {
            return true;
        } else {
            HandlerMethod handlerMethod = (HandlerMethod) handler;
            Method method = ();
            String userAgent = ("User-Agent");
            Boolean hasToken = false;
            if (userAgent!=null&& ()>20){
                hasToken=true;
            }
            ("-------------------");
            if ((() != null || ().getAnnotation() != null) && !hasToken) {
                ("鉴权失败");
                return false;
            } else {
                ("鉴权成功");
                return true;
            }
        }
    }
    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) {
        ("结束");
    }
}

注解

import ;
import ;
import ;
import ;

@Target({, })
@Retention()
public @interface Authorization {
}

控制层

import ;
import ;
import ;

@RestController
@RequestMapping("/test")
public class TestController1 {
    @GetMapping(value = "/1")
    public String getInfo() {

        return "gatherLoginInfo";
    }
    @Authorization
    @GetMapping(value = "/2")
    public String getInfo2() {

        return "gatherLoginInfo";
    }
}
