CXF部署到weblogic

CXF项目在tomcat下可以正常运行，部署到weblogic下出现各种问题。现记录下解决思路。

1.一开始到网上一通狂搜，搜索CXF+weblogic、搜索具体错误，搜到的最多的原因是包冲突了，但是按照解决方案却不能解决我的问题

严重: exception raied when invoking setter public final void org.apache.cxf.wsdl11.WSDLManagerImpl.setBus(org.apache.cxf.Bus)java.lang.reflect.InvocationTargetExceptionat sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57)at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)at java.lang.reflect.Method.invoke(Method.java:606)

2.网上的方案解决不了问题，只能回归到问题本身，通过分析出错信息发现上面的异常都是下面的异常导致的，问题的根本是最下面这个异常。最后这个异常出现在      org.objectweb.asm.Frame中，这个异常是试图创建大小为负的数组，猜测是jar包冲突导致的，于是修改weblogic.xml配置，这个配置是优先引用应用程序的类，而不是weblogic的。

<?xml version="1.0" encoding="UTF-8" ?><weblogic-web-app xmlns="http://www.bea.com/ns/weblogic/weblogic-web-app"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.bea.com/ns/weblogic/weblogic-web-app http://www.bea.com/ns/weblogic/weblogic-web-app/1.0/weblogic-web-app.xsd"><container-descriptor><!-- <prefer-web-inf-classes>true</prefer-web-inf-classes> --><prefer-application-packages><package-name>antlr.*</package-name><package-name>org.objectweb.asm.*</package-name></prefer-application-packages></container-descriptor></weblogic-web-app> 

3.配置修改后，上述错误果然没有了，报出新的异常

八月 03, 2017 10:09:04 上午 org.apache.cxf.ws.discovery.internal.WSDiscoveryServiceImpl startup警告: Could not start WS-Discovery Service.javax.xml.ws.WebServiceException: org.apache.cxf.service.factory.ServiceConstructionException: Failed to create service.at org.apache.cxf.jaxws.EndpointImpl.doPublish(EndpointImpl.java:375)

4.按照上面的思路，最根本的问题还是最后这个异常，再次猜测有可能是jar包冲突，配置weblogic.xml，异常没有消失，说明并不是jar包冲突(weblogic也没有CXF的jar包)

5.既然这个思路走不通了，就去网上搜索，终于发现一篇有价值的博客，在jboss下部署CXF出现这个运行时异常的解决方案(http://blog.csdn.net/wuxuguang123/article/details/43676265)，这篇文章是从源码的角度去分析的，从而发现是ALLOW_INSECURE_PARSER这个系统属性导致这个异常的

 然而这篇文章给出的是jboss下的解决方案，不过没关系，继续搜索这个属性以及他的解决方案

6.搜索"org.apache.cxf.stax.allowInsecureParser"发现一篇解决这个问题的文章(http://blog.csdn.net/koudailidexiaolong/article/details/52239670)，文章中采用的是监听器启动时重新设置系统属性来解决这个问题的

package com.shensu.listener;import java.util.Properties;import javax.servlet.ServletContextEvent;import javax.servlet.ServletContextListener;public class SealManageListener implements ServletContextListener  {@Overridepublic void contextDestroyed(ServletContextEvent arg0) {// TODO Auto-generated method stub}@Overridepublic void contextInitialized(ServletContextEvent arg0) {Properties props = System.getProperties();        props.setProperty("org.apache.cxf.stax.allowInsecureParser", "1");}}

7.最后部署，启动weblogic，控制台没有报错，在浏览器中访问wsdl地址http://localhost:7001/TestCXF/webservice/childinfo?wsdl成功

8.整个过程最大的收获是：不要太依赖搜索引擎，要学会看异常信息，学会看源代码

9.最后出现了异常，有时间再改
