SpringBoot學習筆記之攔截器使用

Springboot 攔截器

1)、創建我們自己的攔截器類並實現 HandlerInterceptor 接口。 

public class LiyjInterceptor implements HandlerInterceptor{

@Override

public void afterCompletion(HttpServletRequest arg0,

HttpServletResponse arg1, Object arg2, Exception arg3)

throws Exception {

System.out.println(this.getClass().getName()+ "<------>afterCompletion");

}

@Override

public void postHandle(HttpServletRequest arg0, HttpServletResponse arg1,

Object arg2, ModelAndView arg3) throws Exception {

System.out.println(this.getClass().getName() + "<------>postHandle");

}

@Override

public boolean preHandle(HttpServletRequest arg0, HttpServletResponse arg1,

Object arg2) throws Exception {

System.out.println(this.getClass().getName() + "<------>preHandle");

return true;

}

}

2)、創建一個Java類繼承WebMvcConfigurerAdapter，並重寫 addInterceptors 方法。 實例化我們自定義的攔截器，然後將對像手動添加到攔截器鏈中（在addInterceptors方法中添加）。

@Configuration

public class SpringInterceptorRegister extends WebMvcConfigurerAdapter {

@Override

public void addInterceptors(InterceptorRegistry registry) {

registry.addInterceptor(new LiyjInterceptor()).addPathPatterns("/**");

registry.addInterceptor(new ShanInterceptor()).addPathPatterns("/freemarker/**");

super.addInterceptors(registry);

}

}
