如何使用Jersey在REST Web服务中为服务类指定多个包名称

Question

如何<param-value>为<param-name>servlet的<init-param>标记下的给定指定多个.以下是我的web.xml文件:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
  <display-name>com.vogella.jersey.first</display-name>
 <servlet>
    <servlet-name>Jersey REST Service</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
     <!-- Register resources and providers under com.vogella.jersey.first package. -->
    <init-param>
        <param-name>jersey.config.server.provider.packages</param-name>
        <param-value>com.vogella.jersey.first</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>Jersey REST Service</servlet-name>
    <url-pattern>/rest/*</url-pattern>
  </servlet-mapping>
</web-app> 

参数jersey.config.server.provider.packages定义了Jersey将在哪个包中查找Web服务类.

我想在这里指定多个包名,因为我的服务类在不同的包中.像下面这样的东西,但它们都不起作用:

1)多个 <param-value>

<init-param>
    <param-name>jersey.config.server.provider.packages</param-name>
    <param-value>com.vogella.jersey.first</param-value>
    <param-value>com.vogella.jersey.second</param-value>
</init-param>

2)多个 <init-param>

<servlet>
    ...
    <init-param>
        <param-name>jersey.config.server.provider.packages</param-name>
        <param-value>com.vogella.jersey.first</param-value>
    </init-param>
    <init-param>
        <param-name>jersey.config.server.provider.packages</param-name>
        <param-value>com.vogella.jersey.second</param-value>
    </init-param>

我该怎么做呢？

Answer 1

您不能<param-value>为单个指定多个<param-name>.

改用它:

<init-param>
    <param-name>jersey.config.server.provider.packages</param-name>
    <param-value>com.pack.first;com.pack.rest.second</param-value>
</init-param>

;,,可以用作分隔符.
