Spring5+CXF整合开发REST之一次坑旅

前言

花了挺长时间查找问题，也就不在乎再花点时间记录一下了。

问题起源：
一直使用Spring5和CXF开发 SOAP的Web service，因为业务需求需要提供REST的Web Service, 看起来很容易的事，导入Rest的包应该就可以了。但是接下来是就是一系列的问题了。

为了重现和解决这些问题，新建一个Project(基于maven 的 web 项目)用于测试

测试项目

1.pom.xml

</project>

Spring 配置文件： applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>

 <bean id="restService" class="com.oscar999.rest.RestService" /><jaxrs:server id="restService" address="/api"><jaxrs:serviceBeans><ref bean="restService" /></jaxrs:serviceBeans></jaxrs:server><!-- <jaxrs:providers><bean class="org.codehaus.jackson.jaxrs.JacksonJsonProvider"/></jaxrs:providers>-->

3.服务接口

package com.oscar999.rest;import javax.ws.rs.GET;
import javax.ws.rs.Path;import com.oscar999.WsResponse;public interface RestServiceI {@GET@Path("/get")public WsResponse get();
}

4.服务实现

/*** @Title: RestService.java* @Package com.oscar999* @Description: TODO* @author oscar999* @date Oct 17, 2018 2:19:54 PM* @version V1.0*/package com.oscar999.rest;import com.oscar999.WsResponse;/*** @ClassName: RestService* @Description: TODO* @author oscar999*/public class RestService implements RestServiceI {public WsResponse get() {WsResponse wsResponse = new WsResponse();wsResponse.setSuccessFlag("S");wsResponse.setRtnValue("hello world");wsResponse.setMessage("No message");return wsResponse;}
}

踩过的坑

坑1. invalid LOC header
jar档下载不完全，文件损坏。
使用maven下载较多的jar时，这种问题应该出现的机率还是比较大。细节的错误信息类似：

填坑法：

有的情形下Eclipse会自动帮我们找出这些未下载完全的文件，在Problem视图可以看到类似：

但是有的时候就没那么幸运了。网上是说可以通过maven test发现，但是好像对于eclipse没识别的也发现不了。

最后的办法就是对每个jar点击一下，看是否会出错。

找到有问题的，删除之，重新下载。
注：这里出现问题的是 stax2-api-3.1.4.jar

坑2：The main resource set specified [D:\devworkspace\ecpphotonspace.metadata.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\restws] is not valid

这个问题出现在使用eclipse的server插件运行，右键Run as Server的状况。
原因是有些文件无法copy或server插件的目录：
.metadata.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps
导致找不到资源，启动失败。
常见的方法是remove项目之后重新添加，如果实在顽固的话，就只能maven install后 copy到tomcat或其他服务器目录下执行了。

坑3： Error creating bean with name ‘XXXXservice’: Invocation of init method failed; nested exception is org.apache.cxf.service.factory.ServiceConstructionException
创建服务bean失败，这是此次被坑了时间最长的，也是自己大意了。
有一种原因是依赖库的版本不对，导致这个原因。逐一对应之后发现没问题。

No resource classes found：资源没找到

实在没辙， Debug一下

没有找到服务的类。看一下Bean的配置

<bean id="restService" class="com.oscar999.rest.RestService" /><jaxrs:server id="restService" address="/api"><jaxrs:serviceBeans><ref bean="restService" /></jaxrs:serviceBeans>
</jaxrs:server>

bean 的id 和jaxrs:server 的id 相同，导致被覆盖，找不到RestService Bean.
