jersey2.26+spring5+jpa一步步搭建restful服务

前言

　首先，为什么想选择Jersey做restful服务呢？我个人比较喜欢它的插件化设计，可以方便的注入自己的全局处理逻辑。再一个就是可以生成wadl描述文件，供查询服务方法。所以在学习spring的过程中，特意抽时间做了jersey+spring集成的验证。在本次搭建的过程中，为了在jersey服务中启动spring事务，从网上查阅了不少。先是看到com.sun.jersey例子，后来发现版本比较低，后转过头去看org.glassfish.jersey。吭吭哧哧服务启动了，却又发现无法通过spring容器实例化服务，无法开启事务，拿不到懒加载数据。又查阅资料来回调试，解决版本不匹配的问题，将jersey-spring3升级成jersey-spring4。摸索的过程总是枯燥的，好在总算是一个个问题的排查解决，终究实现了自己想要的功能! 在这里把我自己摸索过程中涉及到的重点位置分享给大家，希望能对大家有所帮助。

一、关于Jersey

　Jersey RESTful 框架是开源的RESTful框架, 实现了JAX-RS (JSR 311 & JSR 339) 规范。它扩展了JAX-RS 参考实现， 提供了更多的特性和工具， 可以进一步地简化 RESTful service 和 client 开发。尽管相对年轻，它已经是一个产品级的 RESTful service 和 client 框架。与Struts类似，它同样可以和hibernate,spring框架整合。

　jersey1.X使用的是sun的com.sun.jersey

　jersey2.X使用的是glassfish的org.glassfish.jersey

二、集成环境说明

　Java：1.8.0_152、SpringMVC：5.0.1.RELEASE、Jersey：2.26-b04、开发工具：eclipse、涉及技术点：springmvc,spring-security,spring data jpa,jersey

三、项目结构简介

　3.1、simm.spring.web是web层，simm.spring.restapi是jersey服务层

　3.2、父级spring-web的POM文件中配置spring jar包依赖

   3.3、simm.spring.restapi子项目下的POM文件中配置jersey jar包依赖。jersey-spring4这个jar包是jersey,spring框架整合的关键，起桥接作用，使用时可根据需要排除掉jersey指定的jar包文件。

  4.2、关于contextConfigLocation与listener的配置简单说明

　搭建过程中，发现启动项目时老是提示找不到applicationContext.xml文件。通过调试代码，发现jersey-spring4-2.26-b04.jar下继承接口WebApplicationInitializer实现了启动类 SpringWebApplicationInitializer。这段逻辑会从WebApplicationContext中去读取contextConfigLocation配置项，假如读不到值就会自动设置初始化路径applicationContext.xml。因此就有了web.xml文件中的context-param>contextConfigLocation 的配置，根据源码配置系统全局监听器ContextLoaderListener和RequestContextListener。全局监听的配置可以保证jersey的servlet容器同样能够读取到spring容器中的对象。

　　

　4.3、关于jersey请求的servlet容器配置说明

• servlet-class:org.glassfish.jersey.servlet.ServletContainer
• servlet-mapping>url-pattern:/api/*，即restful服务请求从api层级开始
• init-param[javax.ws.rs.Application]：simm.spring.restapi.config.MyRestfulService,这个类是自己项目对jersey的配置说明，声明自己的resouce服务路径，并注册一些全局插件

　

　4.4、simm.spring.restapi.config.MyRestfulService 类源码说明。

　在网上查阅资料时，有些文章指出需要注入 RequestContextFilter过滤器，个人测试示例中发现还没有受到影响，在我的代码里不用这个过滤器也照样可以正常运行。可能还没有涵盖到这块功能。调用packages方法,指定服务资源所在的包名。此外，还注册了json、log、异常处理、跨域处理几个插件。

package simm.spring.restapi.config;

import org.glassfish.jersey.jackson.JacksonFeature;
import org.glassfish.jersey.logging.LoggingFeature;
import org.glassfish.jersey.server.ResourceConfig;
import org.glassfish.jersey.server.spring.scope.RequestContextFilter;

public class MyRestfulService extends ResourceConfig {
     public MyRestfulService(){
        // 需要注入spring组件解析过滤器
        register(RequestContextFilter.class);
        // 加载resources
        packages("simm.spring.restapi.resource");
        // 注册数据转换器
        register(JacksonFeature.class);
        // 注册日志
        register(LoggingFeature.class);
        // 异常处理
        register(ExceptionHandler.class);
        // 跨域过滤器注册
        register(CorsFilter.class);
    }
}

• 异常处理器代码

@Provider
public class ExceptionHandler implements ExceptionMapper<Exception> {
    public Response toResponse(Exception exception) {
        // TODO Auto-generated method stub
        //LogKit.error(exception.getMessage(), exception);
        return Response.serverError().entity(new JsonResult(false,exception.getMessage(),exception.toString())).build();
    }
}

• 跨域过滤器代码

package simm.spring.restapi.config;

import javax.ws.rs.container.ContainerRequestContext;
import javax.ws.rs.container.ContainerResponseContext;
import javax.ws.rs.container.ContainerResponseFilter;

public class CorsFilter implements ContainerResponseFilter {
    public void filter(ContainerRequestContext creq, ContainerResponseContext cres) {
        // TODO Auto-generated method stub
        cres.getHeaders().add("Access-Control-Allow-Origin", "*");
        /**
         * 允许的Header值，不支持通配符
         */
        cres.getHeaders().add("Access-Control-Allow-Headers", "origin, content-type, accept, authorization");
        cres.getHeaders().add("Access-Control-Allow-Credentials", "true");
        /**
         * 即使只用其中几种，header和options是不能删除的，因为浏览器通过options请求来获取服务的跨域策略
         */
        cres.getHeaders().add("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS, HEAD");
        /**
         * CORS策略的缓存时间
         */
        cres.getHeaders().add("Access-Control-Max-Age", "1209600");
    }
}

 五、实现一个自己的resource服务ProcessBlockResource

　5.1、ProcessBlockResource源码展示

package simm.spring.restapi.resource;

import java.util.*;
import javax.ws.rs.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Component;
import org.springframework.transaction.annotation.Transactional;
import com.alibaba.fastjson.JSONObject;
import simm.spring.common.utils.JpaUtil;
import simm.spring.entity.ProcessBlock;
import simm.spring.restapi.config.MediaTypeExtend;

@Path("processblock")
@Produces(MediaTypeExtend.APPLICATION_JSON_UTF8)
@Component
@Scope("request")
public class ProcessBlockResource {
    @Autowired
    private JpaUtil _jpaUtil;
    @POST
    @Path("getlist")
    @Transactional
    public List<JSONObject> getList(@FormParam("name") String name) {
        JpaUtil jpaUtil = _jpaUtil;//ApplicationContextUtil.instance.getJpaUtil();
        Map<String, Object> params = new HashMap<>();
        params.put("name", name);
        List<ProcessBlock> list = jpaUtil.list(
                "select u from simm.spring.entity.ProcessBlock u where u.name=:name", params, ProcessBlock.class);
        //System.out.println("准备获取懒加载数据");
        //Set<Node> nodes = list.get(0).getNodeSet();
        List<JSONObject> rows = new ArrayList<JSONObject>();
        list.forEach(a->{
            JSONObject obj = new JSONObject();
            obj.put("Id",a.getId());
            obj.put("Class",a.getClass());
            obj.put("Name",a.getName());
            obj.put("Description",a.getDescription());
            obj.put("SubClass",a.getSubClass());
            //NodeSet 是懒加载对象，如果直接json输出ProcessBlock对象会导致 因session关闭，无法获取关联数据的异常。
            //这里显示的执行一次调用，需要返回的数据最好自己做一次组装
            obj.put("NodeSet",a.getNodeSet().toArray());
            rows.add(obj);
        });
        return rows;
    }
}

　5.2、源码简要解析

• ProcessBlockResource类注解说明

1. @Path：指定资源名为 processblock
2. @Produces：指定资源下服务方法默认返回json格式数据
3. @Component，@Scope("request")：将资源声明为一个请求级别的bean组件,解析后交由spring代理进行实例化

• getList方法注解说明

1. @POST：声明为post请求
2. @Path：指定服务名为 getlist
3. @Transactional：声明开启spring事务对方法的拦截，后面我们会测试事务是否生效

　5.3、启动Tomcat，查看restful服务启动状态。可以访问application.wadl，得到restful服务描述文件。

　　

　5.4、使用SoapUI工具测试一下/processblock/getlist服务

　 从调用返回可以看到，服务调用成功，并成功获取到了懒加载数据NodeSet。说明现在spring容器已经与jersey结合起来，组件初始化以及spring事务的拦截功能都已经正常运转。接下来我们就可以按照这个示例实现自己的restful服务了。关于getList方法中涉及到的实体类以及工具类，如果有需要，请大家参考上篇博文《JPA数据懒加载LAZY配合事务@Transactional使用(三)》

　  

  　至此，jersey+spring5的搭建就完成了。感谢你阅读到最后，如果你有好的意见或建议，欢迎留言，大家一起交流，共同进步。
