如果CXF整合Spring的话，Maven又是构建的web工程，用的是tomcat容器的话，需要如下配置（如果构建的是Java工程，没有使用tomcat容器，则还需要引入jetty的依赖包）

  • 使用CXF开发WebService服务端接口
  • 使用CXF开发WebService客户端
    wsdl2java工具在CXF开发包里
    开发下载地址
    我的是jdk1.7的选择3.1.15版本的，最新版3.2.4需要1.8的jdk
    下载二进制包解压到D盘
    我们需要用到wsdl2java的命令，需要把bin目录配置到环境变量里面
    新建一个客户端工程，找到需要生成java代码的目录，在DOS下进入当前目录，执行命令
D:\svnwork\WS_Client\src\main\java>wsdl2java http://192.168.1.104/helloWorld?wsdl
  • CXF处理JavaBean以及复合类型
  • CXF处理一些Map等复杂类型
  • CXF添加拦截器
  • CXF添加自定义拦截器
  • Spring整合CXF发布WebService服务
  • Spring整合CXF添加拦截器
