Spring Hadoop : unable to set the configuration getting Found ambiguous parameter type

Question

我试图在 Spring XD 中创建一个用于执行 Hadoop 复制的 util 类，我定义了如下配置

<int:channel id="input"/>
<int:service-activator input-channel="input" ref="utilhandler" />
<bean id="utilhandler" class="com.test.hadoop.HadoopUtil"/>
<hdp:configuration  register-url-handler="false" properties-location="${xd.config.home}/hadoop.properties" >
    fs.defaultFS=${fsUri}

</hdp:configuration>
</beans> 

下面是片段 bean 类
导入 org.apache.hadoop.conf.Configuration；
公共(public)类 HadoopUtil 实现 InitializingBean{

      private String destinationDir;
private FsShell shell;
      @Autowired
private Configuration configuration;
public Configuration getHadoopConfiguration()
{
    return configuration;
}

当我执行时，我遇到了异常

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.integration.config.ServiceActivatorFactor
yBean#0': FactoryBean threw exception on object creation; nested exception is java.lang.IllegalArgumentException: Found ambiguous parameter type [class java.lan
g.Void] for method match: [public org.apache.hadoop.conf.Configuration com.test.hadoop.HadoopUtil.getHadoopConfiguration(), public void com.test.hadoop.HadoopUtil.setConfiguration(org.apache.hadoop.conf.Configuration)]
    at org.springframework.beans.factory.support.FactoryBeanRegistrySupport.doGetObjectFromFactoryBean(FactoryBeanRegistrySupport.java:175)

请帮忙

Answer 1

您必须为属性 configuration 定义 setter 和 getter 方法
请对此进行测试，让我们知道它有效或需要更多帮助
