关于使用myeclipse生成webservice报An internal error occurred during 错误_an internal error occurred during: "generating jax-优快云博客

在使用myeclipse创建webservice过程中遇到内部错误，错误信息为'Generating JAX-WS Web Services'和'Unable to create JAXBContext'。问题源于com.asiainfo.cbss.controller.jaxws包下的DebtAgeAnalysis类和实体类同名，导致XML类型冲突。解决方案是修改冲突的方法名称，避免名称重复，从而消除错误。

今天使用myeclipse生成webservice时，一直报错：
An internal error occurred during: “Generating JAX-WS Web Services”.
Unable to create JAXBContext

在启动tomcat时显示如下错误：
Caused by: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions
Two classes have the same XML type name “debtAgeAnalysis”. Use @XmlType.name and @XmlType.namespace to assign different names to them.

在controller的代码如下

@RequestMapping(value = "/debtAgeAnalysis" , consumes = "application/json")
@ResponseBody
public List<DebtAgeAnalysis> debtAgeAnalysis(
        @RequestParam("stat_month") String stat_month,
        @RequestParam("province_code") String province_code,
        @RequestParam("eparchy_code") String eparchy_code,
        @RequestParam("city_code") String city_code,
        @RequestParam("net_type_code") String net_type_code) {
        。。。。
        }

经过仔细检查后发现，在webroot/WEB-INF/wsdl下的QueryControllerService_schema1.xsd文件中
webservice在自动生成时会根据对应的
DebtAgeAnalysis实体和debtAgeAnalysis方法生成对应的代码
由于DebtAgeAnalysis和debtAgeAnalysis两个名称相同，在生成代码时都会起名name=”debtAgeAnalysis”，由于两个名称相同，无法生成，故报错
只需修改debtAgeAnalysis方法的名称即可
