WSO2 版本 5.0.0 自定义用户存储管理器引发 NoClassDefFoundError

Question

我正在尝试在 WSO2IS 5.0.0 版中设置自定义主用户商店管理器。

根据 WSO2IS 5.0.0 版的文档，我必须扩展 UserStoreManager：

import org.wso2.carbon.user.core.jdbc.JDBCUserStoreManager;

public class CustomUserStoreManager extends JDBCUserStoreManager {
...

在 user-mgmt.xml 中，我将 UserStoreManager 更改为引用此 class:

<UserStoreManager class="com.abc.identity.CustomUserStoreManager">
...

在 pom.xml 中，我将其构建为一个包：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

            </configuration>
        </plugin>
    </plugins>
</build>
</project>

但是当我启动 WSO2IS 时，出现以下异常：

[2015-09-29 14:55:07,805] ERROR {org.wso2.carbon.user.core.common.DefaultRealm} -  Cannot create com.abc.identity.CustomUserStoreManager
java.lang.NoClassDefFoundError: org/wso2/carbon/user/core/jdbc/JDBCUserStoreManager

WSO2IS 5.0.0 版的文档没有详细说明如何设置 pom.xml。

请尝试添加插件配置的导出部分

<build>
<plugins>
    <plugin>
        <groupId>org.apache.felix</groupId>
        <artifactId>maven-bundle-plugin</artifactId>
        <version>2.5.0</version>
        <extensions>true</extensions>
        <configuration>
            <instructions>
                <Bundle-SymbolicName>${project.groupId}.${project.artifactId}</Bundle-SymbolicName>
                <Bundle-Name>${project.artifactId}</Bundle-Name>
                <Bundle-Version>0.0.1</Bundle-Version>
                <Private-Package>com.peplink.ecommerce.identity</Private-Package>
                <Import-Package>
                    *
                </Import-Package>
                <Export-Package>
                    org.wso2.carbon.user.core.*
                </Export-Package>
            </instructions>
        </configuration>
    </plugin>
</plugins>

这个pom.xml可以解决NoClassDefFoundError异常。关键是要匹配 WSO2IS 5.0.0 附带的捆绑包版本。
