过滤器

配置过滤器 Filter 来对特定类的方法做是否登录的判断

添加 Filter 的方法：

创建过滤器

public class EncodingFilter implements Filter {
 private static final String CONTENT_TYPE = "text/html;charset=UTF-8";

 public EncodingFilter() {
 }

 public void destroy() {
 }

 public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
     request.setCharacterEncoding("UTF-8");
     response.setCharacterEncoding("UTF-8");
     response.setContentType("text/html;charset=UTF-8");
     chain.doFilter(request, response);
 }

 public void init(FilterConfig filterConfig) throws ServletException {
 }
}

配置类注解 @Configuration
配置类方法注解 @Bean

配置类方法内容：

 FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
 filterRegistrationBean.setOrder(3); // 设置过滤顺序，越小越先执行
 filterRegistrationBean.setFilter(new YourFilter()); // 设置过滤器
 filterRegistrationBean.setName("customFilter"); // 设置过滤器名称
 filterRegistrationBean.addUrlPatterns("*.action"); // 设置使用该过滤器的 Url 特征
 return filterRegistrationBean;
