GeoServer 2.15.2版本跨域問題解決方法

geoserver默認不開啟跨域設置，開啟步驟如下：

嘗試以下幾種方法：

方法一：

1、修改配置文件web.xml，該配置文件的路徑如下

\webapps\geoserver\WEB-INF\web.xml

2、搜索：cross-origin，將注釋的部分解注。

 <!-- Uncomment following filter to enable CORS -->
   <filter>
        <filter-name>cross-origin</filter-name>
        <filter-class>org.eclipse.jetty.servlets.CrossOriginFilter</filter-class>
       <init-param>
           <param-name>chainPreflight</param-name>
           <param-value>false</param-value>
       </init-param>
       <init-param>
           <param-name>allowedOrigins</param-name>
           <param-value>*</param-value>
       </init-param>
       <init-param>
           <param-name>allowedMethods</param-name>
           <param-value>GET,POST,PUT,DELETE,HEAD,OPTIONS</param-value>
       </init-param>
       <init-param>
           <param-name>allowedHeaders</param-name>
           <param-value>*</param-value>
       </init-param>
    </filter>
    
    
    <!-- Uncomment following filter to enable CORS  -->
    <filter-mapping>
        <filter-name>cross-origin</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

3、下載 jetty-servlets jar包，2.15.0對應的版本是 jetty-servlets-9.4.12.v20180830.jar,放在

\geoserver\WEB-INF\lib

4、重啟geoserver,如果報錯，再下載對應 jetty-http 和 jetty-util jar包，放在lib目錄，再次重啟即可，jetty-servlets的jar包要跟jetty-util的jar包版本匹配，jar包下載地址：

https://pan.baidu.com/s/1E9Z4_zGfWWxkJpEZ0yyrPg  ，提取碼  d96c

方法二：

同時下載cors-filter-1.7.jar 跟 java-property-utils-1.9.jar （其他版本可能會導致 geoserver 打不開，測試過用最新版本出現geoserver打不開），同樣放進 lib 文件夾里面，web.xml 增加以下配置：

<filter>
  <filter-name>CORS</filter-name>
  <filter-class>com.thetransactioncompany.cors.CORSFilter</filter-class>
  <init-param>
    <param-name>cors.allowOrigin</param-name>
    <param-value>*</param-value>
  </init-param>
  <init-param>
    <param-name>cors.supportedMethods</param-name>
    <param-value>GET, POST, HEAD, PUT, DELETE</param-value>
  </init-param>
  <init-param>
    <param-name>cors.supportedHeaders</param-name>
    <param-value>Accept, Origin, X-Requested-With, Content-Type, Last-Modified</param-value>
  </init-param>
  <init-param>
    <param-name>cors.exposedHeaders</param-name>
    <param-value>Set-Cookie</param-value>
  </init-param>
  <init-param>
    <param-name>cors.supportsCredentials</param-name>
    <param-value>true</param-value>
  </init-param>
</filter>
<filter-mapping>
  <filter-name>CORS</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

方法三：

下載cors壓縮包 ，提取碼：mdzo ，  然后解壓到 %TOMCAT_PATH%\webapps\geoserver\WEB-INF\classes，然后在 web.xml 配置：

<filter>
  <filter-name>cross-origin</filter-name>
  <filter-class>org.mortbay.servlets.CrossOriginFilter</filter-class>
  <init-param>
    <param-name>allowedOrigins</param-name>
    <param-value>*</param-value>
  </init-param>
  <init-param>
    <param-name>allowedMethods</param-name>
    <param-value>GET,POST</param-value>
  </init-param>
  <init-param>
    <param-name>allowedHeaders</param-name>
    <param-value>x-requested-with,content-type</param-value>
  </init-param>
</filter>
<filter-mapping>
  <filter-name>cross-origin</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

方法四：

在 geoserver 的 web.xml，不需要引入任何庫，進行如下配置

<filter>
  <filter-name>CorsFilter</filter-name>
  <filter-class>org.apache.catalina.filters.CorsFilter</filter-class>
</filter>
<filter-mapping>
  <filter-name>CorsFilter</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

重啟Tomcat。

方法五

基於tomcat安裝的話，可以試試給tomcat整體配跨域策略

解決方案：

一：在tomcat中的lib文件夾下增加兩個jar包

cors-filter-2.4.jar  提取碼 eqlq
java-property-utils-1.9.1.jar   提取碼  ybz7

 

二：在tomcat中的conf文件夾下的web.xml文件中的web-app代碼下增加如下代碼

<filter>
<filter-name>CORS</filter-name>
<filter-class>com.thetransactioncompany.cors.CORSFilter</filter-class>
<init-param>
<param-name>cors.allowOrigin</param-name>
<param-value>*</param-value>
</init-param>
<init-param>
<param-name>cors.supportedMethods</param-name>
<param-value>GET,POST,HEAD,PUT,DELETE</param-value>
</init-param>
<init-param>
<param-name>cors.supportedHeaders</param-name>
<param-value>Accept,Origin,X-Requested-With,Content-Type,Last-Modified</param-value>
</init-param>
<init-param>
<param-name>cors.exposedHeaders</param-name>
<param-value>Set-Cookie</param-value>
</init-param>
<init-param>
<param-name>cors.supportsCredentials</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CORS</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
