这篇文章主要介绍了spring boot加入拦截器Interceptor过程解析,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
1.spring boot拦截器默认有
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 {
}
}
