springboot 用了@ImportResource 配置的拦截器就不起作用了
去掉@ImportResource注解 拦截器就好了
代码:
package com.example.springbootdemo; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.builder.SpringApplicationBuilder; import org.springframework.boot.web.servlet.ServletComponentScan; import org.springframework.boot.web.support.SpringBootServletInitializer; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.ImportResource; @SpringBootApplication @ImportResource(locations={"classpath:config/spring-mongo.xml"}) public class SpringbootdemoApplication extends SpringBootServletInitializer { /** * 让spring boot在tomcat中运行 * @param builder * @return */ @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) { return builder.sources(SpringbootdemoApplication.class); } public static void main(String[] args) { SpringApplication.run(SpringbootdemoApplication.class, args); } }
拦截器继承WebMvcConfigurerAdapter:
package com.example.springbootdemo.Interceptor; import com.example.springbootdemo.Interceptor.LoginInterceptor; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.cache.annotation.EnableCaching; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.ImportResource; import org.springframework.web.servlet.config.annotation.InterceptorRegistry; import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter; @Configuration public class WebConfig extends WebMvcConfigurerAdapter { /** * 自定义静态资源 * @param registry */ @Override public void addResourceHandlers(ResourceHandlerRegistry registry) { //将所有/static/** 访问都映射到classpath:/static/ 目录下 registry.addResourceHandler("/static/**").addResourceLocations("classpath:/static/"); } /** * 拦截器(用户登录验证) * @param registry */ @Override public void addInterceptors(InterceptorRegistry registry) { // addPathPatterns 用于添加拦截规则 // excludePathPatterns 用户排除拦截 registry.addInterceptor(new LoginInterceptor()).addPathPatterns("/**").excludePathPatterns("/user","/login"); super.addInterceptors(registry); } }
拦截方法:
package com.example.springbootdemo.Interceptor; import org.springframework.stereotype.Component; import org.springframework.web.servlet.HandlerInterceptor; import org.springframework.web.servlet.ModelAndView; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; public class LoginInterceptor implements HandlerInterceptor { @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { boolean flag =true; /* User user=(User)request.getSession().getAttribute("user"); if(null==user){ response.sendRedirect("toLogin"); flag = false; }else{ flag = true; }*/ System.out.print("进来了"); return flag; } @Override public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception { } @Override public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception { } }
求解 @ImportResource注解怎么会影响拦截器!!!!!
