利用jdk XML 转成 xsd 再转成 javaBean

第一种方法

首先拿到xml 例如:

<status><sigar  cpu="31.2" memory="87" jvm="79" disk="70" /><jvm><memory free='98567840' total='124780544' max='1825046528'/><memorypool name='PS Eden Space' type='Heap memory' usageInit='32505856' usageCommitted='32505856' usageMax='673710080' usageUsed='2554416'/><memorypool name='PS Old Gen' type='Heap memory' usageInit='87031808' usageCommitted='87031808' usageMax='1368915968' usageUsed='18421456'/><memorypool name='PS Survivor Space' type='Heap memory' usageInit='5242880' usageCommitted='5242880' usageMax='5242880' usageUsed='5236832'/><memorypool name='Code Cache' type='Non-heap memory' usageInit='2555904' usageCommitted='8060928' usageMax='251658240' usageUsed='6854528'/><memorypool name='Compressed Class Space' type='Non-heap memory' usageInit='0' usageCommitted='2490368' usageMax='1073741824' usageUsed='2234352'/><memorypool name='Metaspace' type='Non-heap memory' usageInit='0' usageCommitted='20578304' usageMax='-1' usageUsed='19735120'/></jvm><connector name='"http-nio-8060"'><threadInfo  maxThreads="200" currentThreadCount="10" currentThreadsBusy="1" /><requestInfo  maxTime="249" processingTime="421" requestCount="3" errorCount="0" bytesReceived="0" bytesSent="23445" /><workers><worker  stage="S" requestProcessingTime="736" requestBytesSent="0" requestBytesReceived="0" remoteAddr="0:0:0:0:0:0:0:1" virtualHost="localhost" method="GET" currentUri="/manager/status" currentQueryString="XML=true" protocol="HTTP/1.1" /></workers></connector><connector name='"ajp-nio-8061"'><threadInfo  maxThreads="200" currentThreadCount="10" currentThreadsBusy="0" /><requestInfo  maxTime="0" processingTime="0" requestCount="0" errorCount="0" bytesReceived="0" bytesSent="0" /><workers></workers></connector></status>

通过:http://www.xmlforasp.net/CodeBank/System_Xml_Schema/BuildSchema/BuildXMLSchema.aspx 这个网站在线转成xsd

新增文件保存为 test.xsd 编码utf-16 改成utf-8

cmd 进入到文件下执行:

xjc test.xsd -p test.java

然后就可以看到生成的文件了,  就是这么的简单;

第二种方法

Jaxb

JAXB官网:http://jaxb.java.net/

API链接 :http://jaxb.java.net/nonav/2.2.5/docs/api/

文档    http://jaxb.java.net/tutorial/   

1. 利用trang.jar将Xml 转换成xsd

 Trang 是一种命令行的可以XML生成XSD的工具,生成XML文件对应的XSD文件只需要3个简单的步骤:

第一步  下载Trang

http://www.thaiopensource.com/relaxng/trang.html 上下载trang-version.zip

利用trang 生成xsd后, 之后的 动作跟上面一样;
