我正在尝试按照link1中的说明进行操作 和link2将数据源存储在jndi中，以便每个mule应用程序都可以访问它而无需重新定义它。 我得到了@David Dossot的帮助，并按照@Spina的建议制作了这个bean：
import java.util.Map;
import java.util.Map.Entry;
import org.springframework.beans.factory.InitializingBean;
import org.springframework.jndi.JndiTemplate;
public class JndiExporter implements InitializingBean {
private final JndiTemplate template = new JndiTemplate();
private Map<String, Object> jndiMapping = null;
@Override
public void afterPropertiesSet() throws Exception {
for(Entry<String, Object> addToJndi: jndiMapping.entrySet()){
template.bind(addToJndi.getKey(), addToJndi.getValue());
}
}
public void setJndiMapping(Map<String, Object> jndiMapping) {
this.jndiMapping = jndiMapping;
}
}
然后是一个简单的骡子应用程序：
<?xml version="1.0" encoding="UTF-8"?>

不幸的是它不起作用，它在启动时出现以下错误：

@Genjosanzo回答我的春豆成了：

但不幸的是，我得到的错误与之前相同。
答案 0 :(得分：1)
您获得的错误意味着您必须设置系统属性以启用jndiContext。
如果您想在弹簧配置中执行此操作，则应添加如下所示的bean
<bean id="systemJndiPrereqs" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
<property name="targetObject" value="#{@systemProperties}" />
<property name="targetMethod" value="putAll" />
<property name="arguments">
<!-- The new Properties -->
<util:properties>
<prop key="#{ T(javax.naming.Context).URL_PKG_PREFIXES }">org.apache.naming</prop>
</util:properties>
</property>
</bean>
