MULE Esb xml 到对象转换器

Question

我正在尝试利用 xml 到 mule 中的对象转换器，同时将 xml 有效负载转换为 Java Bean（客户）。这是我的简单流程。我看到的异常如下

异常堆栈是： 1. 客户（com.thoughtworks.xstream.mapper.CannotResolveClassException） com.thoughtworks.xstream.mapper.DefaultMapper:56（空） 2. 客户（com.thoughtworks.xstream.mapper.CannotResolveClassException）（org.mule.api.transformer.TransformerException） org.mule.module.xml.transformer.XmlToObject:76 (http://www.mulesoft.org/docs/site/current3/apidocs/org/mule/api/transformer/TransformerException.html) -------------------------------------------------- ------------------------------ 根异常堆栈跟踪： com.thoughtworks.xstream.mapper.CannotResolveClassException：客户 在 com.thoughtworks.xstream.mapper.DefaultMapper.realClass(DefaultMapper.java:56) 在 com.thoughtworks.xstream.mapper.MapperWrapper.realClass(MapperWrapper.java:30) 在 com.thoughtworks.xstream.mapper.DynamicProxyMapper.realClass(DynamicProxyMapper.java:55) + 3 个（设置调试级别日志记录或“-Dmule.verbose.exceptions=true”为所有内容）

流程

<?xml version="1.0" encoding="UTF-8"?>

<mule xmlns:http="http://www.mulesoft.org/schema/mule/http" xmlns:mulexml="http://www.mulesoft.org/schema/mule/xml" xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation" xmlns:spring="http://www.springframework.org/schema/beans" version="EE-3.4.1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-current.xsd

        <logger level="INFO" doc:name="Logger"/>
    </flow>
</mule>

XML：

<CUSTOMER xmlns:xlink="w3.org/1999/xlink">
 ;
 <ID>4</ID>
 <FIRSTNAME>Sylvia</FIRSTNAME>
 <LASTNAME>Ringer</LASTNAME>
 <STREET>365 College Av.</STREET>
 <CITY>Dallas</CITY>
</CUSTOMER>

Answer 1

您需要在mulexml:xml-to-object-transformer中添加别名：

<mulexml:alias name="CUSTOMER" class="com.abc.dto.CUSTOMER" />

此外，没有理由将类名全部大写，因此请重命名您的类并为其命名：

<mulexml:alias name="CUSTOMER" class="com.abc.dto.Customer" />
