在 CXF wsdl2java 中设置 Java 合规性级别
我是 CXF 的新手,正在尝试从 WSDL 创建客户端。我过去使用过 Metro 和 Axis。我下载了 apache-cxf-2.3.3 并使用 wsdl2java 生成客户端存根。我使用 Maven 并使用以下命令设置我的 pom:
<properties>
<cxf.version>2.3.3</cxf.version>
</properties>
<dependencies>
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-frontend-jaxws</artifactId>
<version>${cxf.version}</version>
</dependency>
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-transports-http</artifactId>
<version>${cxf.version}</version>
</dependency>
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-ws-security</artifactId>
<version>${cxf.version}</version>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<inherited>true</inherited>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.5</source>
<target>1.5</target>
<optimize>true</optimize>
<debug>true</debug>
</configuration>
</plugin>
</plugins>
</build>
当我构建项目时,我收到以下错误:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile) on project client-cxf: Compilation failure: Compilation failure:
[ERROR] \Devel\Projects\Client-CXF\src\main\java\my\webservice\ServiceRuntimeException.java:[38,149] cannot find symbol
[ERROR] symbol : method required()
似乎
[ERROR] \Devel\Projects\Client-CXF\src\main\java\my\snmpv2\MyService.java:[76,8] cannot find symbol
[ERROR] symbol : constructor Service(java.net.URL,javax.xml.namespace.QName,javax.xml.ws.WebServiceFeature[])
[ERROR] location: class javax.xml.ws.Service
这些问题与生成的代码使用 Java 6 功能(XmlElementRef 的“require”元素,服务的新构造函数),但 CXF Maven 依赖项适用于 Java 5。
有没有办法指定生成的代码应符合 Java 5?
I’m brand new to CXF and am trying to create a client from WSDL. I have used Metro and Axis in the past. I downloaded apache-cxf-2.3.3 and used wsdl2java to generate the client stubs. I use Maven and set it up my pom with this:
<properties>
<cxf.version>2.3.3</cxf.version>
</properties>
<dependencies>
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-frontend-jaxws</artifactId>
<version>${cxf.version}</version>
</dependency>
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-transports-http</artifactId>
<version>${cxf.version}</version>
</dependency>
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-ws-security</artifactId>
<version>${cxf.version}</version>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<inherited>true</inherited>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.5</source>
<target>1.5</target>
<optimize>true</optimize>
<debug>true</debug>
</configuration>
</plugin>
</plugins>
</build>
When I build the project, I get these errors:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile) on project client-cxf: Compilation failure: Compilation failure:
[ERROR] \Devel\Projects\Client-CXF\src\main\java\my\webservice\ServiceRuntimeException.java:[38,149] cannot find symbol
[ERROR] symbol : method required()
and
[ERROR] \Devel\Projects\Client-CXF\src\main\java\my\snmpv2\MyService.java:[76,8] cannot find symbol
[ERROR] symbol : constructor Service(java.net.URL,javax.xml.namespace.QName,javax.xml.ws.WebServiceFeature[])
[ERROR] location: class javax.xml.ws.Service
It appears that the problems are related to the fact that the generated code uses Java 6 features (“require” element for XmlElementRef, new constructors for Service) yet the CXF Maven dependencies are for Java 5.
Is there a way to specify that the generated code should be Java 5 compliant?

实际上,CXF 的 wsdl2java 命令行工具的代码与 Java 5 兼容,只是可能与 Java 6 不兼容。原因是它生成的代码兼容 JAX-WS 2.2 和 JAXB 2.2。然而,Java 6 中包含的这些 API 的版本仅为 2.1。
有几个选项:
1) 最简单的方法是在 wsdl2java 命令中添加“-fe jaxws21”,使其生成符合 jaxws 2.1 标准的代码而不是 2.2
2) 将 2.2 api jar 添加到 JDK 的认可目录中
3) 配置maven 中的编译器插件“认可”2.2 jar
Actually, the code that CXF's wsdl2java command line tool is compatible with Java 5, it's just likely not compatible for Java 6. The reason is that it generates code that is JAX-WS 2.2 and JAXB 2.2 compliant. However, the versions of those API's included in Java 6 are only 2.1.
There are a few options:
1) Easiest is to add "-fe jaxws21" to the wsdl2java command to have it generate jaxws 2.1 compliant code instead of 2.2
2) Add the 2.2 api jars to the endorsed directory of your JDK
3) Configure the compiler plugin in maven to "endorse" the 2.2 jars
wsdl2java 文档 没有提到任何用于指定 Java 版本的选项。
您可以尝试使用 Maven cxf-codegen-plugin 生成客户端存根,它应该尊重 Maven 编译器的源版本和目标版本。
如果这不起作用,您可以通过更改 pom 中的源行和目标行来将 Maven 配置为使用 Java 6,如下所示:
The wsdl2java documentation doesn't mention any options for specifying the Java version.
You could try using the Maven cxf-codegen-plugin to generate the client stubs, which should respect the Maven compiler's source and target versions.
If that doesn't work, you could configure Maven to use Java 6 by changing the source and target lines in the pom, like so:
