我希望使用Wso2 ESB 4.8.1确保访问休息服务的安全性。 我的服务由一个http get请求组成，该请求调用ESB上定义的代理。 代理定义了我的http get服务并使用UsernameToken安全性进行保护。 这是配置文件：
<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
name="prova3"
transports="https"
statistics="disable"
trace="disable"
startOnLoad="true">
<target>
<outSequence>
<send/>
</outSequence>
<endpoint>
<address uri="http://localhost:8080/download/"/>
</endpoint>
</target>
<parameter name="ScenarioID">scenario1</parameter>
<enableSec/>
<policy key="conf:/repository/axis2/service-groups/prova3/services/prova3/policies/UTOverTransport"/>
<description/>
</proxy>
当我尝试调用服务时，esb抛出以下异常：
