Jersey使用

最近在看《Java RESTful Web Service实战》,以前都是用的RESTEasy,Maven配置:

<dependency>
	<groupId>org.jboss.resteasy</groupId>
	<artifactId>resteasy-jaxb-provider</artifactId>
	<version>3.0.13.Final</version>
</dependency>
<dependency>
	<groupId>org.jboss.resteasy</groupId>
	<artifactId>resteasy-jaxrs</artifactId>
	<version>3.0.13.Final</version>
</dependency>
<dependency>
	<groupId>org.jboss.resteasy</groupId>
	<artifactId>resteasy-jackson2-provider</artifactId>
	<version>3.0.13.Final</version>
</dependency>
<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-client</artifactId>
    <version>3.0.13.Final</version>
</dependency>

但是使用Jersey(版本:2.x)时,发现并不是那么顺利。这里整理一下,先贴完整的Maven配置:

<dependency>
	<groupId>org.glassfish.jersey.core</groupId>
	<artifactId>jersey-client</artifactId>
	<version>2.26</version>
</dependency>
	<dependency>
    <groupId>org.glassfish.jersey.containers</groupId>
    <artifactId>jersey-container-servlet</artifactId>
    <version>2.26</version>
</dependency>
	<dependency>
	<groupId>org.glassfish.jersey.inject</groupId>
	<artifactId>jersey-hk2</artifactId>
	<version>2.26</version>
</dependency>
<dependency>
	<groupId>org.glassfish.jersey.bundles</groupId>
	<artifactId>jaxrs-ri</artifactId>
	<version>2.4</version>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.jaxrs</groupId>
    <artifactId>jackson-jaxrs-json-provider</artifactId>
    <version>2.4.1</version>
</dependency>

web.xml配置:

<servlet>
	<servlet-name>jersey</servlet-name>
	<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
	<init-param>
		<param-name>jersey.config.server.provider.packages</param-name>
		<param-value>com.webservice.rs</param-value>
	</init-param>
	<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
	<servlet-name>jersey</servlet-name>
	<url-pattern>/services/*</url-pattern>
</servlet-mapping>

然后这里有几个错误:

java.lang.IllegalStateException: InjectionManagerFactory not found.

	at java.util.Optional.orElseThrow(Optional.java:290)

缺少依赖com.fasterxml.jackson.jaxrs

如果依赖都有了,还是没有反应,访问时提示404,可能是web.xml的包名参数名称配置错了,2.xjersey.config.server.provider.packages,旧版本是com.sun.jersey.config.property.packages
