有没有办法让 CXF 在与 Web 服务通信时忽略 maxElementCount

Question

我正在使用SPring 3.2.11.RELEASE和CXF 2.7.18。 我的 SPring 应用程序上下文文件中有这个，这是与 Web 服务通信所必需的......

    <jaxws:client id="myWebServiceClient"
            serviceClass="org.mainco.bsorg.MyWebService"
            address="${wsdl.url}"
    />
    <cxf:bus>
            <cxf:properties>
            <entry key="org.apache.cxf.stax.maxElementCount" value="10000000"/>
            </cxf:properties>
    </cxf:bus>

在我的 Maven pom.xml 文件中，我为插件配置了这个......

                    <plugin>
                            <groupId>org.codehaus.mojo</groupId>
                            <artifactId>jaxws-maven-plugin</artifactId>
                            <version>2.4.1</version>
                            <executions>
                                    <execution>
                                            <goals>
                                                    <goal>wsimport</goal>
                                            </goals>
                                            <configuration>
                                                    <target>2.1</target>
                                                    <wsdlDirectory>${basedir}/src/wsdl</wsdlDirectory>
                                                    <sourceDestDir>${basedir}/src/main/java</sourceDestDir>
                                                    <packageName>org.mainco.bsorg</packageName>
                                                    <vmArgs>
                                                            <vmArg>-Djavax.xml.accessExternalSchema=all</vmArg>
                                                    </vmArgs>
                                            </configuration>
                                    </execution>
                            </executions>
                    </plugin>

毫无疑问，当我对我的 Web 服务执行特定调用时，我会收到此错误......

如果我将 maxElementCount 值从"10000000"更改为"1000000

"，则会出现上述错误，并显示"超出最大子元素数限制 (1000000("。 有没有办法让 CXF 完全忽略 maxElementCount 限制？ 不得不摆弄最大值是一种痛苦。 我愿意使用natoher技术在Spring中配置Web服务，但是如果您建议使用，请提供我需要的Maven和Spring配置。

Answer 1

您是否尝试过设置 org.apache.cxf.stax.maxChildElements 属性？

您似乎正在尝试覆盖错误的属性maxElementCount而不是maxChildElements。

请参阅此处的文档。
