Fuse_012：基础入门之一：cxf-basic

环境：JBoss Fuse 6.2.0 + Maven 3.2.2

1. 学习重点
（1）从零开始构建 cxf JAX-WS Web Service。

2. 修改 settings.xml，内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<settings xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.1.0 http://maven.apache.org/xsd/settings-1.1.0.xsd" xmlns="http://maven.apache.org/SETTINGS/1.1.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   
    <profiles>
       
        <profile>
            <id>fusesource-repository</id>
            <repositories>
                <repository>
                    <id>fusesource</id>
                    <url>http://repo.fusesource.com/nexus/content/groups/public/</url>                               
                    <releases>
                        <enabled>true</enabled>
                    </releases>                    
                    <snapshots>
                        <enabled>false</enabled>
                    </snapshots>
                </repository>
                <repository>
                    <id>apache-public</id>
                    <url>https://repository.apache.org/content/groups/public/</url>
                    <releases>
                        <enabled>true</enabled>
                    </releases>                    
                    <snapshots>
                        <enabled>false</enabled>
                    </snapshots>                   
                </repository>
            </repositories>
            <pluginRepositories>
                <pluginRepository>
                    <releases />
                    <snapshots>
                        <enabled>false</enabled>
                    </snapshots>
                    <id>fusesource-plugin-repository</id>
                    <url>http://repo.fusesource.com/nexus/content/groups/public/</url>
                </pluginRepository>
            </pluginRepositories>
        </profile>      
       
    </profiles>
   
    <activeProfiles>
        <activeProfile>fusesource-repository</activeProfile>      
    </activeProfiles>
   
</settings>

注意，必须增加 pluginRepositories 部分，并指向 http://repo.fusesource.com/nexus/content/groups/public/，否则运行 mvn clean install 时会报告如下错误：
（1）[ERROR] Failed to execute goal org.apache.cxf:cxf-java2ws-plugin:3.0.4.redhat-620133:java2ws (process-classes) on project cxf-basic: Execution process-classes of goal org.apache.cxf:cxf-java2ws-plugin:3.0.4.redhat-620133:java2ws failed: A required class was missing while executing org.apache.cxf:cxf-java2ws-plugin:3.0.4.redhat-620133:java2ws: org/apache/cxf/helpers/CastUtils
（2）[ERROR] Plugin org.apache.cxf:cxf-java2ws-plugin:3.0.4.redhat-620133 or one of its dependencies could not be resolved: Failure to find org.apache.cxf:cxf-java2ws-plugin:jar:3.0.4.redhat-620133 in http://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced -> [Help 1]

错误（1）是由错误（2）引起的，根本原因是 org.apache.cxf:cxf-java2ws-plugin:jar:3.0.4.redhat-620133 无法下载，该文件实际在 http://repo.fusesource.com/nexus/content/groups/public/org/apache/cxf/cxf-java2ws-plugin/ 中，不在  http://repo.maven.apache.org/maven2 中，因此下载不了。增加 pluginRepositories 部分，并指向 http://repo.fusesource.com/nexus/content/groups/public/ 后，问题消失。

3. 使用 Maven 构建
（1）mvn archetype:generate -DarchetypeGroupId=io.fabric8.archetypes -DarchetypeArtifactId=karaf-soap-archetype -DarchetypeVersion=1.2.0.redhat-133 -DgroupId=org.fusesource.example -DartifactId=cxf-basic -Dversion=1.0-SNAPSHOT -Dfabric8-profile=cxf-basic-profile
（2）修改 cxf-basic/src/test/resources/request.xml，修改后内容如下：
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    <soap:Body>
        <ns2:sayHi xmlns:ns2="http://example.fusesource.org/">      
            <arg0>John Doe</arg0>
        </ns2:sayHi>
    </soap:Body>
</soap:Envelope>
注意，必须修改，否则 mvn -Ptest 会报如下错误：
Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.293 sec <<< FAILURE! - in org.fusesource.example.SoapTest
sendRequest(org.fusesource.example.SoapTest)  Time elapsed: 0.167 sec  <<< ERROR!
java.io.IOException: Server returned HTTP response code: 500 for URL: http://localhost:8181/cxf/HelloWorld
    at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1627)
    at org.fusesource.example.SoapTest.sendRequest(SoapTest.java:83)

（3）cd cxf-basic
（4）mvn clean install

4. 部署 、卸载
（1）./fuse
（2）osgi:install -s mvn:org.fusesource.example/cxf-basic/1.0-SNAPSHOT
（3）osgi:list
（4）mvn -Ptest
（5）http://localhost:8181/cxf
（6）http://localhost:8181/cxf/HelloWorld?wsdl
（7）osgi:uninstall <id>
