我在为 CXF REST 服务 API 项目集成 enunciate 和 ant 时遇到错误。方法 getFeeItemsByCapID() 中存在错误。我试图在源代码中找到答案，但没有结果。谁对错误有任何想法？谢谢你的帮助。如果您有任何提示。

蚂蚁脚本

<path id="enunciate.classpath">
    <fileset dir="${enunciate.home}/lib">
        <include name="*.jar"/>
        </fileset>
        <!--include (optional) spring module-->
        <fileset dir="${enunciate.home}/lib/modules/cxf">
            <include name="*.jar"/>
        </fileset>
        <fileset dir="${java.home}">
            <include name="lib/tools.jar"/>
        </fileset>
    </path>

    <taskdef name="enunciate" classname="org.codehaus.enunciate.main.EnunciateTask">
        <classpath refid="enunciate.classpath"/>
    </taskdef>  

    <enunciate basedir="java/" configFile="enunciate.xml">
        <include name="**/*.java"/>
        <classpath refid="enunciate.classpath"/>
        <export artifactId="war.file" destination="d:/myapp.war"/>
        <javacArgument argument="-g"/>
    </enunciate>

Java 代码

@GET
@RecordDetailSecurity(RecordDetailSectionType.FEE)
@Path("/{recordIds}/fees/")
@Produces(MediaType.APPLICATION_JSON)
@JsonView(Views.PublicView.class)
public ResponseModel getFeeItemsByCapID(@PathParam("recordIds") String recordIds,
        @QueryParam("fields") @DefaultValue("") String fields) throws Exception

我在自定义注释中找到了根本原因。似乎是因为注释没有默认值。当我删除方法的自定义注释或在注释定义中附加默认值时。异常将消失。但是注解接受一个枚举，在业务逻辑中注解没有默认值。我们总是需要设置枚举值以供使用。但是，为什么注解总是需要默认值呢？有人知道原因吗？

@Target( {ElementType.TYPE, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
public @interface RecordDetailSecurity
{
    RecordDetailSectionType value(); //append default value such as "default RecordDetailSectionType.ADDITIONAL_INFORMATION;"
}

@RecordDetailSecurity(RecordDetailSectionType.FEE)
public ResponseModel getFeeItemsByCapID(@PathParam("recordIds") String recordIds,
    @QueryParam("fields") @DefaultValue("") String fields) throws Exception

关于注释默认值错误，我创建了一个示例项目再试一次。它运作良好。现在，我需要改变我原来的看法。我的错。:) 首先，我的项目编译成功，之前没有明确 ant 目标。然而枚举“RecordDetailSectionType”实际上属于另一个罐子。我没有将jar包含在阐明类路径中，因此无法识别自定义的注释类型值。很抱歉对于这个误会。
