爲什麼war文件不是在eclipse中的spring mvc框架中構建的？

Question

我想構建一個maven構建並創建.war文件。它顯示了錯誤：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project EmpReg: Compilation failure: Compilation failure: [ERROR] /E:/Java_Project/EmployeeOnlineRegistrationForm/src/main/java/EmployeeOnlineRegistrationForm/controller/EmployeeRegistrationController.java:[13,47] cannot find symbol [ERROR] symbol: class CrossOrigin [ERROR] location: package org.springframework.web.bind.annotation [ERROR] /E:/Java_Project/EmployeeOnlineRegistrationForm/src/main/java/EmployeeOnlineRegistrationForm/controller/EmployeeRegistrationController.java:[22,2] cannot find symbol [ERROR] symbol: class CrossOrigin

Answer 1

我已經解決了這個問題。 1）我已經下載cors-filter-2.2.1.jar添加它。 2）我已經加入行家依存性的pom.xml：

<dependency> 
    <groupId>com.thetransactioncompany</groupId> 
    <artifactId>cors-filter</artifactId> 
    <version>2.2.1</version> 
    </dependency> 

3）我已延長我的控制器和覆蓋方法：

public class EmployeeRegistrationController extends OncePerRequestFilter { 
@Override 
     protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException { 

      response.addHeader("Access-Control-Allow-Origin", "*"); 
      if (request.getHeader("Access-Control-Request-Method") != null && "OPTIONS".equals(request.getMethod())) { 
       //LOG.trace("Sending Header...."); 
       // CORS "pre-flight" request 
       response.addHeader("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE"); 
       // response.addHeader("Access-Control-Allow-Headers", "Authorization"); 
       response.addHeader("Access-Control-Allow-Headers", "Content-Type"); 
       response.addHeader("Access-Control-Max-Age", "1"); 
      } 
      filterChain.doFilter(request, response); 
     } 


} 

4）我已經在web.xml中加入過濾器：

<filter> 
     <filter-name>cors</filter-name> 
     <filter-class>EmployeeOnlineRegistrationForm.controller.EmployeeRegistrationController</filter-class> <!-- your package name and filter class --> 
    </filter> 
    <filter-mapping> 
     <filter-name>cors</filter-name> 
     <url-pattern>/*</url-pattern> 
    </filter-mapping>
