問題描述
今天在給SpringBoot項目配置攔截器的時候發(fā)現(xiàn)怎么都進不到攔截器的方法里面，在搜索引擎上看了無數(shù)篇關于配置攔截器的文章都沒有找到解決方案。
就在我準備放棄的時候，在 CSDN 上發(fā)現(xiàn)了一篇文章，說的是SpringBoot 用了@ImportResource 配置的攔截器就不起作用了。于是我就趕緊到Application啟動類看了一眼，果然項目中使用了@ImportResource 注解用于配置系統(tǒng)的參數(shù)。
代碼如下：
啟動類配置
package com.xx.xxx;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;@EnableDiscoveryClient@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class, ThymeleafAutoConfiguration.class})@SpringBootApplication// 注意這里 ！！！！@ImportResource(locations={"classpath:config/application-*.xml"})@EnableHystrixpublic class Application extends SpringBootServletInitializer { public static void main(String[] args) { SpringApplication.run(Application.class, args); }}攔截器配置
package com.xx.xxx.config;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;@Configurationpublic class WebMvcConfig extends WebMvcConfigurerAdapter { /** * 攔截器(用戶登錄驗證) * @param registry */ @Override public void addInterceptors(InterceptorRegistry registry) { // addPathPatterns 用于添加攔截規(guī)則 // excludePathPatterns 用戶排除攔截 registry.addInterceptor(new LoginInterceptor()).addPathPatterns("/**").excludePathPatterns("/user","/login"); super.addInterceptors(registry); }}攔截器實現(xiàn)
package com.xx.xxx.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 { private final static Logger LOGGER = LoggerFactory.getLogger(LoginInterceptor.class); @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { LOGGER.info("******進來了******"); return true; } @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 { }}具體為什么使用@ImportResource注解會影響攔截器的配置，如果有機會研究一下源碼或許能夠找到答案。
PS : SpringBoot 版本 1.5.2
