springboot自定义拦截器，需要继承WebMvcConfigurerAdapter并重写addInterceptors。
======以下仅为示例，代码沿用上一章=====
具体实现如下：
①创建MyInterceptor.java文件
@Configuration //声明配置
public class MyInterceptor extends WebMvcConfigurerAdapter {
@Override
public void addInterceptors(InterceptorRegistry registry) {
HandlerInterceptor interceptor = new HandlerInterceptor() {
@Override
public boolean preHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o) throws Exception {
System.out.println("拦截器启动:"+httpServletRequest.getRequestURL());
return false;
}
@Override
public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, ModelAndView modelAndView) throws Exception {
}
@Override
public void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) throws Exception {
}
};
//addPathPatterns 需要拦截的路由，excludePathPatterns不需要拦截的路由
registry.addInterceptor(interceptor).addPathPatterns("/**").excludePathPatterns("/login");
}
}
其中@Configuration 注解是必须的。
②，启动类中配置@SpringBootApplication。（我的拦截器写在webdev.interceptor下）
编辑
③，Controller
@RestController
public class WcbDevController {
@RequestMapping("/getPerInfo")
public Object getPerInfo(){
PersonModel personModel = new PersonModel();
personModel.setBirthday(new Date());
personModel.setNickName("不要喷香水");
return personModel;
}
@RequestMapping("/login")
public Object login(){
JSONObject mav = new JSONObject();
mav.put("status",true);
mav.put("msg","登录");
return mav;
}
④，启动项目，分别访问查看结果（请自行验证，这里就不截图了！）
