    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
