SpringFramework手动注册RequestMapping API

SpringFramework手动注册RequestMapping API接口

业务场景：最近遇到一个特殊需求，需要手动注册RequestMapping ，使用SpringFramework项目里的RequestMappingInfoHandlerMapping进行手动注册

package portal.configure;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.condition.ConditionalOnExpression;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.http.HttpStatus;
import org.springframework.social.connect.web.HttpSessionSessionStrategy;
import org.springframework.social.connect.web.SessionStrategy;
import org.springframework.util.StringUtils;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.context.request.ServletWebRequest;
import org.springframework.web.filter.OncePerRequestFilter;
import org.springframework.web.servlet.mvc.method.RequestMappingInfo;
import org.springframework.web.servlet.mvc.method.RequestMappingInfoHandlerMapping;

import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;


@Configuration
@ConditionalOnExpression("${auth.isEnable : false}")
public class RequestMappingConfiguration { private SessionStrategy sessionStrategy = new HttpSessionSessionStrategy(); @Autowired public void setRequestMapping(RequestMappingInfoHandlerMapping mapping) throws NoSuchMethodException { mapping.registerMapping(RequestMappingInfo .paths("/api/test").methods(RequestMethod.GET).build(), this, this.getClass().getMethod("reqMethod", HttpServletRequest.class, HttpServletResponse.class)); } public void reqMethod(HttpServletRequest request, HttpServletResponse response) throws Exception { sessionStrategy.setAttribute(new ServletWebRequest(request), "userCode", "admin"); response.setStatus(HttpStatus.OK.value()); response.setCharacterEncoding("utf-8"); response.setContentType (  "application/json; charset=utf-8"); PrintWriter printWriter = response.getWriter(); printWriter.write("{ \"status\":"+HttpStatus.OK.value()+", \"desc\":\""+ "api接口调用成功!" +"\"}"); printWriter.flush(); } @Bean @Primary public FilterRegistrationBean myFilterRegistration() { FilterRegistrationBean registration = new FilterRegistrationBean(); registration.setFilter(new OncePerRequestFilter() { @Override protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException { String origin = request.getHeader("origin"); if (StringUtils.isEmpty(origin)) { origin = "*"; } response.setHeader("Access-Control-Allow-Origin", origin); response.setHeader("Access-Control-Allow-Credentials", "true"); filterChain.doFilter(request, response); } }); registration.addUrlPatterns("/api"); return registration; }

}

linux环境测试api接口

[www@localhost ~]$ curl http://127.0.0.1:8080/api/test
{ "status":200, "desc":"api接口调用成功!"}
