問(wèn)題描述
今天在給SpringBoot項(xiàng)目配置攔截器的時(shí)候發(fā)現(xiàn)怎么都進(jìn)不到攔截器的方法里面,在搜索引擎上看了無(wú)數(shù)篇關(guān)于配置攔截器的文章都沒(méi)有找到解決方案。
就在我準(zhǔn)備放棄的時(shí)候,在 CSDN 上發(fā)現(xiàn)了一篇文章,說(shuō)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(dòng)類(lèi)看了一眼,果然項(xiàng)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(dòng)類(lèi)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"}) @EnableHystrix public 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; @Configuration public class WebMvcConfig extends WebMvcConfigurerAdapter { /** * 攔截器(用戶登錄驗(yàn)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(shí)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(jìn)來(lái)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(huì)影響攔截器的配置,如果有機(jī)會(huì)研究一下源碼或許能夠找到答案。
PS : SpringBoot 版本 1.5.2
