访问控制允许来源：*在tomcat中

tomcat

我想在tomcat容器中设置默认的http标头-

访问控制允许来源：*

从stackoverslow和Google的各种不同链接中，大多数都指向一种资源。这再次说明了如何做。我已经复制了相同的内容，但是仍然没有显示标题。这是我所做的：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

<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。

由于未将jar文件作为项目的一部分而出现该问题。我只是将其包含在tomcat lib中。web.xml现在可以在工程中使用以下内容：

<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>

并且下面是您的项目依赖项：

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