spring-boot 加入拦截器Interceptor

1.spring boot拦截器默认有

HandlerInterceptorAdapter

AbstractHandlerMapping

UserRoleAuthorizationInterceptor

LocaleChangeInterceptor

ThemeChangeInterceptor

2.配置spring mvc的拦截器WebMvcConfigurerAdapter

public class WebAppConfig extends WebMvcConfigurerAdapter

3.实现添加拦截器方法

public void addInterceptors(InterceptorRegistry registry){

}
registry.addInterceptor可以通过此方法添加拦截器, 可以是spring提供的或者自己添加的

4.实例部分

public class WebAppConfig extends WebMvcConfigurerAdapter{
public static void main(String[] args) {
SpringApplication.run(WebAppConfig.class, args);
}

/**
* 配置拦截器
* @author lance
* @param registry
*/
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new UserSecurityInterceptor()).addPathPatterns("/user/**");
}
}

UserSecurityInterceptor代码
public class UserSecurityInterceptor implements HandlerInterceptor {

@Override
public boolean preHandle(HttpServletRequest request,
HttpServletResponse response, Object handler) throws Exception {

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 {

}

}
