我已经用javax.ws尝试了非常简单的restful教程,我对maven依赖有问题。 web.xml文件如下所示:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1">
<servlet>
<servlet-name>jersey-servlet</servlet-name>
<servlet-class>
com.sun.jersey.spi.container.servlet.ServletContainer
</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>service</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>jersey-servlet</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
</web-app>
像这样的和maven依赖:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>groupId</groupId>
<artifactId>untitled40</artifactId>
<version>1.0-SNAPSHOT</version>
<dependencies>
<dependency>
<groupId>javax.ws.rs</groupId>
<artifactId>javax.ws.rs-api</artifactId>
<version>2.0</version>
</dependency>
<dependency>
<groupId>com.sun.jersey</groupId>
<artifactId>jersey-server</artifactId>
<version>1.2</version>
</dependency>
</dependencies>
</project>
和Class是:
package service;
import javax.ws.rs.*;
@Path("hesab")
public class App {
@Path("textc")
@GET
@Produces("text/plain")
public String recit(){
return "got it";
}
}
问题是,当我将JAR文件添加到WEB-INF的lib文件夹中时,它将工作并连接到我的服务,但是当我尝试添加maven依赖项并删除lib文件夹时,它不起作用!你能告诉我这是什么问题吗?
答案 0 :(得分:0)
我确实遇到了同样的问题。
更改这个
的javax依赖项<dependency>
<groupId>org.glassfish.jersey.core</groupId>
<artifactId>jersey-server</artifactId>
<version>2.6</version>
</dependency>
<dependency>
<groupId>org.glassfish.jersey.containers</groupId>
<artifactId>jersey-container-servlet</artifactId>
<version>2.6</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.jaxrs</groupId>
<artifactId>jackson-jaxrs-json-provider</artifactId>
<version>2.4.1</version>
</dependency>
并创建此类
package ***.services;
import java.util.HashSet;
import java.util.Set;
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
import ***UsuarioResource;
/**
* The Class PortalAppConfiguration.
*/
@ApplicationPath("api")
public class ApiConfiguration extends Application {
@Override
public Set<Class<?>> getClasses()
{
final Set<Class<?>> classes = new HashSet<>();
classes.add(UsuarioResource.class);//your resource
return classes;
}
}
让你的web.xml像这样,因为在这个新的实现中,它没有被使用
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1">
</web-app>
