Question

我搜索了很多关于这个问题的主题，有些人告诉我使用resteasy-servlet-intialler，有些人使用RestEasyBootstrap，但它无法正常工作而只是回复404页面。它让我疯狂。你可以帮助我出？

  <servlet>
    <servlet-name>Resteasy</servlet-name>
    <servlet-class>org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher</servlet-class>
    <load-on-startup>1</load-on-startup>
    <init-param>
        <param-name>javax.ws.rs.Application</param-name>
        <param-value>com.restfully.shop.services.ShoppingApplication</param-value>
    </init-param>
</servlet>
<servlet-mapping>
    <servlet-name>Resteasy</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

这就是简单的应用程序：

@ApplicationPath("/services")
public class ShoppingApplication extends Application {

    private Set<Object> singletons =new HashSet<Object>();
    private Set<Class<?>> empty=new HashSet<Class<?>>();

    public ShoppingApplication()
    {
        singletons.add(new CustomerResource());
    }

    @Override
    public Set<Class<?>> getClasses() {
        return empty;
    }

    @Override
    public Set<Object> getSingletons() {
        return singletons;
    }
}

这里是gradle：

dependencies {
    compile group:'org.jboss.resteasy',name:'resteasy-jaxrs',version:'3.1.2.Final'
    compile group:'org.jboss.resteasy',name:'resteasy-jackson-provider',version:'3.1.2.Final'
    compile group:'org.jboss.resteasy',name:'resteasy-guice',version:'3.1.2.Final'
    compile group: 'org.jboss.resteasy',name:'resteasy-servlet-initializer',version:'3.1.2.Final'
    testCompile group: 'junit', name: 'junit', version: '4.11'
}

删除@ApplicationPath注释，因为由于您的web.xml配置，它是多余的。

将web.xml更改为：

<context-param>
    <param-name>resteasy.servlet.mapping.prefix</param-name>
    <param-value>/services</param-value>
</context-param>

<servlet>
    <servlet-name>Resteasy</servlet-name>
    <servlet-class>org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher</servlet-class>
    <load-on-startup>1</load-on-startup>
    <init-param>
        <param-name>javax.ws.rs.Application</param-name>
        <param-value>com.restfully.shop.services.ShoppingApplication</param-value>
    </init-param>
</servlet>
<servlet-mapping>
    <servlet-name>Resteasy</servlet-name>
    <url-pattern>/services/*</url-pattern>
</servlet-mapping>

注意更新的url-pattern。
