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

问题描述

我想在我的 tomcat 容器中设置一个默认的 http 标头 -

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

访问控制允许来源:*

从 stackoverslow 和 google 上的各种不同链接，大多数都指向了一个 资源.这个 再次说明了如何去做.我已经复制了相同的内容，但仍然没有显示标题.这就是我所做的:1) 复制tomcat/lib文件夹下的cors.jar文件2)在web.xml中插入这段文字

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，我很无助.我的 tomcat 版本是 -6.0.6.请帮忙.

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

推荐答案

这个问题的出现是因为项目中没有包含 jar 文件.我只是将它包含在 tomcat lib 中.现在在 web.xml 中使用以下内容:

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>

以及您的项目依赖项中的以下内容:

And the below in your project dependency:

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