这篇博客探讨了在使用JAXB进行XML到对象转换时遇到的问题。具体表现为尝试将`ParamMethod`对象转换为`InterfaceContainer`，导致`ClassCastException`。博主详细展示了`MethodContainer`、`ParamMethod`类的结构，并分析了可能的错误原因。

@XmlRootElement(name="interfaceContainer")
public class InterfaceContainer {
   //接口名
   private String interfaceName;
   //接口方法
   private List<MethodContainer> methods;
   //接口描述
   private String comment;
   //接口创建人
   private String creator;
   //接口创建时间
   private Date createDate;
   //接口修改人
   private String modifier;
   //修改时间
   private Date updateDate;
   //生成时间
   private Date generatedDate;
   //状态
   private int state;
   //get set
   @XmlElement
   public String getInterfaceName() {
       return interfaceName;
   }

   public void setInterfaceName(String interfaceName) {
       this.interfaceName = interfaceName;
   }
   @XmlElementWrapper(name = "methods")
   @XmlElement(name = "method")
   public List<MethodContainer> getMethods() {
       return methods;
   }
   public void setMethods(List<MethodContainer> methods) {
       this.methods = methods;
   }
   @XmlElement
   public String getComment() {
       return comment;
   }
   public void setComment(String comment) {
       this.comment = comment;
   }
   @XmlElement
   public String getCreator() {
       return creator;
   }
   public void setCreator(String creator) {
       this.creator = creator;
   }
   @XmlElement
   public Date getCreateDate() {
       return createDate;
   }
   public void setCreateDate(Date createDate) {
       this.createDate = createDate;
   }
   @XmlElement
   public String getModifier() {
       return modifier;
   }
   public void setModifier(String modifier) {
       this.modifier = modifier;
   }
   @XmlElement
   public Date getUpdateDate() {
       return updateDate;
   }
   public void setUpdateDate(Date updateDate) {
       this.updateDate = updateDate;
   }
   @XmlElement

   public Date getGeneratedDate() {
       return generatedDate;
   }
   public void setGeneratedDate(Date generatedDate) {
       this.generatedDate = generatedDate;
   }
   @XmlElement
   public int getState() {
       return state;
   }

   public void setState(int state) {
       this.state = state;
   }

这个是最外层的对象，

public class MethodContainer {
   //方法名称
   private String methodName;
   //方法参数
   private List<ParamMethod> param;
   //方法返回值
   private ParamMethod returned;
   //方法修饰词
   private String decorated;
   //方法体
   private String methodBody;
   //get set方法
   @XmlElement
   public String getMethodName() {
       return methodName;
   }
   public void setMethodName(String methodName) {
       this.methodName = methodName;
   }
   @XmlElementWrapper(name = "params")
   @XmlElement(name = "param")
   public List<ParamMethod> getParam() {
       return param;
   }
   public void setParam(List<ParamMethod> param) {
       this.param = param;
   }
   @XmlElement
   public String getDecorated() {
       return decorated;
   }
   public void setDecorated(String decorated) {
       this.decorated = decorated;
   }
   @XmlElement
   public ParamMethod getReturned() {
       return returned;
   }
   public void setReturned(ParamMethod returned) {
       this.returned = returned;
   }
   @XmlElement
   public String getMethodBody() {
       return methodBody;
   }
   public void setMethodBody(String methodBody) {
       this.methodBody = methodBody;
   }

这个是中间对象

@XmlRootElement(name="interfaceContainer")
public class ParamMethod {
   //参数类型

   private String paramClazz;
   //参数名

   private String paramName;
   //get set
   @XmlElement
   public String getParamClazz() {
       return paramClazz;
   }
   public void setParamClazz(String paramClazz) {
       this.paramClazz = paramClazz;
   }
   @XmlElement
   public String getParamName() {
       return paramName;
   }
   public void setParamName(String paramName) {
       this.paramName = paramName;
   }
