问题

Spring Boot拦截器，拦截返回的中文乱码问题。

代码结构如下：

  1. public class demoFilter extends GenericFilterBean {
  3.   @Override
  4.   public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
  5.     HttpServletRequest request = (HttpServletRequest) servletRequest;
  6.     HttpServletResponse response = (HttpServletResponse) servletResponse;
  8.     response.getWriter().write("您好");
  9.     return;
  10.   }
  11. }

FilterConfig：

  1. @Configuration
  2. public class FilterConfig {
  4.   @Bean
  5.   public FilterRegistrationBean jwtFilter() {
  6.     final FilterRegistrationBean registrationBean = new FilterRegistrationBean();
  7.     registrationBean.setFilter(new demoFilter());
  8.     registrationBean.addUrlPatterns("/*");
  9.     return registrationBean;
  10.   }
  11. }

Controller：

  1. @RestController
  2. public class Demo {
  4.   @RequestMapping(value = "demo", method = RequestMethod.GET)
  5.   public String getStr(HttpServletRequest request, HttpServletResponse response) {
  6.     return "demo";
  7.   }
  8. }

SpringApplication：

  1. @SpringBootApplication
  2. public class DemoApplication {
  4.   public static void main(String[] args) {
  5.     SpringApplication.run(DemoApplication.class, args);
  6.   }
  7. }

项目启动后，访问 http://localhost:8080/demo

实际返回：??

期望返回：您好

我在 application.properties 中添加了以下配置：

  1. spring.http.encoding.force=true
  2. spring.http.encoding.charset=UTF-8
  3. spring.http.encoding.enabled=true
  4. server.tomcat.uri-encoding=UTF-8

浏览器访问，返回：

Postman访问返回正确结果。

我想请问，如何完美解决这个问题，使浏览器返回正确的中文。
