本文来自于oschina，本文主要介绍了一个在 spring boot 项目添加Jeresy框架的详细过程，希望对大家能有所帮助 。
Jeresy是一个轻量级的JAX-RS框架
添加Jeresy 2.x的依赖
compile group: 'org.glassfish.jersey.core', name: 'jersey-client', version: '2.26'compile group: 'org.glassfish.jersey.containers', name: 'jersey-container-servlet', version: '2.26'compile group: 'org.glassfish.jersey.media', name: 'jersey-media-json-jackson', version: '2.26'build.gradle文件内容:
buildscript {ext {springBootVersion = '1.5.8.RELEASE'}repositories {mavenLocal()maven{ url "http://SVN:8081/nexus/content/groups/public"}mavenCentral()jcenter()}dependencies {classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")}} Apply plugin: 'JAVA'apply plugin: 'eclipse'apply plugin: 'org.springframework.boot' group = 'com.example'version = '0.0.1-SNAPSHOT'sourceCompatibility = 1.8[compileJava, compileTestJava]*.options*.encoding = 'UTF-8' repositories {mavenLocal()maven{ url "http://SVN:8081/nexus/content/groups/public"}mavenCentral()jcenter()} dependencies {compile('org.springframework.boot:spring-boot-configuration-processor')compile('org.springframework.boot:spring-boot-starter-web')compile group: 'org.glassfish.jersey.core', name: 'jersey-client', version: '2.26'compile group: 'org.glassfish.jersey.containers', name: 'jersey-container-servlet', version: '2.26'compile group: 'org.glassfish.jersey.media', name: 'jersey-media-json-jackson', version: '2.26'testCompile('org.springframework.boot:spring-boot-starter-test')}创建一个 spring boot 项目
在IDE里一路next
Spring Boot启动APP
package com.example.demo; import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication // @wjw 是Sprnig Boot项目的核心注解,主要目的是开启自动配置.public class JerseyApplication { public static void main(String[] args) {SpringApplication.run(JerseyApplication.class, args);} } 注册jersey servlet
这和原来在 web.xml 配置的是一样的,设置 Mapping,设置 init 初始化参数,对应的 servlet class name .
所有的rest/*请求都将被 ServletContainer jersey servlet 容器接管.
package com.example.demo; import org.glassfish.jersey.servlet.ServletContainer;import org.glassfish.jersey.servlet.ServletProperties;import org.springframework.boot.web.servlet.ServletRegistrationBean;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;@Configurationpublic class ConfigBean {@Beanpublic ServletRegistrationBean jerseyServlet() {//手动注册servletServletRegistrationBean registrationBean = new ServletRegistrationBean(new ServletContainer(), "/rest/*");registrationBean.addInitParameter(ServletProperties.JAXRS_APPLICATION_CLASS,JerseyResourceConfig.class.getName()); return registrationBean;}}创建jersey Resources
packages方式是采用扫描包的方式批量注册
register 是单个注册
package com.example.demo; import org.glassfish.jersey.server.ResourceConfig;import org.springframework.web.filter.RequestContextFilter; public class JerseyResourceConfig extends ResourceConfig { public JerseyResourceConfig() {/** Servlet Filter that exposes the request to the current thread, through both org.springframework.context.i18n.LocaleContextHolder and RequestContextHolder. To be registered as filter in web.xml.<br/> Alternatively, Spring's org.springframework.web.context.request.RequestContextListener and Spring's org.springframework.web.servlet.DispatcherServlet also expose the same request context to the current thread.<br/> This filter is mainly for use with third-party servlets, e.g. the JSF FacesServlet. Within Spring's own web support, DispatcherServlet's processing is perfectly sufficient.<br/>*/register(RequestContextFilter.class);// 加载资源文件,这里直接扫描com.example.demo.controller下的所有api packages("com.example.demo.controller"); //register(HelloController.class); //@wjw_note: 这种是注册单个的 JAX-RS component!}}创建jersey Controller,使用 JAX-RS 规范的注解进行设置即可
【Spring Boot与JAX-RS框架Jersey的完美搭配】package com.example.demo.controller; import javax.ws.rs.GET;import javax.ws.rs.Path;import javax.ws.rs.PathParam;import javax.ws.rs.Produces;import javax.ws.rs.core.MediaType;import com.example.demo.User;@Path("/user/")public class HelloController {@Path("{id}")@GET@Produces(MediaType.APPLICATION_JSON)public User hello(@PathParam("id") Long id) {User user = new User();user.setID(id);user.setUserName("mvc.");return user;}}
