在apache tomcat 7.0上运行它时的jersey 2.7问题 [英] jersey 2.7 issue while running it on apache tomcat 7.0
问题描述
我正在使用apache tomcat 7.0和eclipse创建一个jersey应用程序。
我在eclipse中创建了一个动态Web项目，并将资源文件定义为： -
I am creating a jersey application using apache tomcat 7.0 and eclipse. I have created a dynamic web project in eclipse and have defined a resource file as:-
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
// Plain old Java Object it does not extend as class or implements
// an interface
// The class registers its methods for the HTTP GET request using the @GET annotation.
// Using the @Produces annotation, it defines that it can deliver several MIME types,
// text, XML and HTML.
// The browser requests per default the HTML MIME type.
//Sets the path to base URL + /hello
@Path("/hello")
public class Hello {
// This method is called if TEXT_PLAIN is request
@GET
@Produces(MediaType.TEXT_PLAIN)
public String sayPlainTextHello() {
return "Hello Jersey";
}
// This method is called if XML is request
@GET
@Produces(MediaType.TEXT_XML)
public String sayXMLHello() {
return "<?xml version=\"1.0\"?>" + "<hello> Hello Jersey" + "</hello>";
}
// This method is called if HTML is request
@GET
@Produces(MediaType.TEXT_HTML)
public String sayHtmlHello() {
return "<html> " + "<title>" + "Hello Jersey" + "</title>"
+ "<body><h1>" + "Hello Jersey" + "</body></h1>" + "</html> ";
}
}
还创建了web.xml文件如下所示 -
web.xml file is also created as below-
<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
<display-name>de.vogella.jersey.first</display-name>
<servlet>
<servlet-name>Jersey REST Service</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>jersey.config.server.provider.packages</param-name>
<param-value>de.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>
以下jar文件已被添加到web-inf的lib文件夹中，并且也在目录结构中部署war文件后的web-apps。
Following jar files have been added to lib folder in web-inf and are also coming in directory structure in web-apps after war file is deployed.
显示错误后将立即启动tomcat和war文件时出现的问题：
The problem which is coming as soon as i start tomcat and war file is deployed following error is displayed:

我在lib文件夹中添加了以下jar：
I have added following jars to lib folder:
**/de.vogella.jersey.first/WebContent/WEB-INF/lib/guava-16.0.1.jar
/de.vogella.jersey.first/WebContent/WEB-INF/lib/jersey-client.jar
/de.vogella.jersey.first/WebContent/WEB-INF/lib/jersey-common.jar
/de.vogella.jersey.first/WebContent/WEB-INF/lib/jersey-container-servlet-core.jar
/de.vogella.jersey.first/WebContent/WEB-INF/lib/jersey-container-servlet.jar
/de.vogella.jersey.first/WebContent/WEB-INF/lib/jersey-server.jar**
但是这个错误仍然存在，请告诉我哪里出错了。
But still this error is coming, please tell me where i am going wrong.
推荐答案
最后解决了。请检查下面的jar文件。使用这么多jar文件来实现REST服务真是令人厌恶。可能是重新安装或轻松休息比运动衫更好。
At last solved. Please check below jar files. It is disgusting to use this number of jar files to implement REST services. May be restlet or easy rest is better than jersey.
hk2-api-2.2.0.jar
hk2-locator-2.2.0.jar
hk2-utils-2.2.0.jar
javassist-3.18.1-GA.jar
javax.annotation-api-1.2.jar
javax.inject-2.2.0.jar
javax.ws.rs-api-2.0.jar
jersey-client.jar
jersey-common.jar
jersey-container-servlet.jar
jersey-container-servlet-core.jar
jersey-guava-2.8.jar
jersey-server.jar,
validation-api-1.1.0.Final.jar
希望有人觉得这很有用。上面已知使用泽西版2.8
Hope someone may find this useful. The above is known working with jersey version 2.8
