springboot的安全验证一

1.创建拦截器类

public class LoginInterceptor implements HandlerInterceptor { @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { System.out.println("interceptor preHandle"); return true; } @Override public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception { System.out.println("interceptor postHandle"); } @Override public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception { System.out.println("interceptor afterCompletion"); } }

2.创建controller类

@RestController//@Controller+@ResponseBody public class UserController { @GetMapping("/user/getUser")//@RequestMapping+get请求 public User getUser() { User user=new User(); user.setId(1); user.setUserName("张三"); user.setUserPassword("123"); return user;//user对象会转换成json字符串 } @GetMapping("/user/hello")//@RequestMapping+get请求 public String hello() { return "hello spring boot"; } @GetMapping("/user/index")//@RequestMapping+get请求 public String index() { return "index"; } }

3.创建拦截器的注册类

@Configuration public class WebConfig implements WebMvcConfigurer { @Override public void addInterceptors(InterceptorRegistry registry) { //需要拦截的路径 String[] addPathPatterns= { "/user/**" }; //不需要拦截的路径 String[] excludePathPatterns= { "/user/hello", "/user/index" }; //注册指定的拦截器,可以用注册多个 InterceptorRegistration interceptor=registry.addInterceptor(new LoginInterceptor()); interceptor.addPathPatterns(addPathPatterns);//添加需要拦截的路径 interceptor.excludePathPatterns(excludePathPatterns);//添加不需要拦截的路径 } }

4.启动springboot项目运行测试即可
