Access-Control-Allow-Origin：*在tomcat中 [英] Access-Control-Allow-Origin: * in tomcat

问题描述

我想在我的tomcat容器中设置默认的http标头 -

I want to set a default http header in my tomcat container -

Access-Control-Allow-Origin：*

Access-Control-Allow-Origin: *

来自stackoverslow和谷歌的各种不同链接，大多数都指向资源。 这个再次说明如何做到这一点。我已经复制了相同的内容，但仍未显示标题。
这就是我所做的：
1）在tomcat的/ lib文件夹中复制cors.jar文件
2）在web.xml中插入此文本

From various different links on stackoverslow and from google, most have pointed to a resource. This again says same on how to do it. I have replicated the same, but still the header is not shown. This is what I have done: 1) Copied cors.jar file in /lib folder of tomcat 2) Inserted this text in web.xml

<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>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>

它不起作用，我很无奈。我的tomcat版本是-6.0.6。请帮助。

It doesn't work and I am helpless. My tomcat version is -6.0.6. Please help.

推荐答案

问题出现是因为不包括 jar 文件作为项目的一部分。我只是把它包含在tomcat lib中。使用 web.xml 中的以下内容现在可以使用：

The issue arose because of not including jar file as part of the project. I was just including it in tomcat lib. Using the below in web.xml works now:

<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>
        org.springframework.web.filter.DelegatingFilterProxy
    </filter-class>
</filter>

 <filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

<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.supportsCredentials</param-name>
        <param-value>false</param-value>
    </init-param>
    <init-param>
        <param-name>cors.supportedHeaders</param-name>
        <param-value>accept, authorization, origin</param-value>
    </init-param>
    <init-param>
        <param-name>cors.supportedMethods</param-name>
        <param-value>GET, POST, HEAD, OPTIONS</param-value>
    </init-param>
</filter>


<filter-mapping>
    <filter-name>CORS</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

以下项目依赖项：

<dependency>
    <groupId>com.thetransactioncompany</groupId>
    <artifactId>cors-filter</artifactId>
    <version>1.3.2</version>
</dependency>
