使用CXF学习WebService时，出现如下错误：

public static void main(String[] args) {
    ServerFactoryBean factoryBean = new ServerFactoryBean();
    String address = "http://192.168.0.36:8082/ws/jax";
    factoryBean.setAddress(address);
    factoryBean.setServiceClass(PersonServiceImpl.class);
    factoryBean.create();
    System.out.println(address + "?WSDL");
}

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/apache/cxf/frontend/ServerFactoryBean : Unsupported major.minor version 51.0

	at com.spring.cxf.ws.PhoneWebService.main(PhoneWebService.java:9)

错误原因：

使用jdk6和apache-cxf-3.1.2，但cxf-3.1.2已经不支持jdk6，需要jdk7以上

jdk版本对照：

J2SE 8 = 52,

J2SE 7 = 51,

J2SE 6.0 = 50,

J2SE 5.0 = 49,

JDK 1.4 = 48,

JDK 1.3 = 47,

JDK 1.2 = 46,

JDK 1.1 = 45

解决方法一：

把CXF换成apache-cxf-2.7.17

解决方法二：

升级jdk到7
