JAXB似乎是重新编码新行的char [英] JAXB seems to be re-encoding new line char

问题描述

我有以下代码...

  public static final String NEWLINE = String.format（％n） ; 
 ... 
 StringBuilder b = new StringBuilder（）; 
 ... 
在b.append（新行）; 
 return b.toString（）; 
  

然而，当我在SOAPUI中运行它并查看RAW时，它看起来像是再次增加它新行变成

 & #xD; 
  

所以而不是

 < SOAPEnvelope> 1，name，value 
 2，name，value< SOAPEnvelope> 
  

它显示为...

 <的SoapEnvelope大于1，名称，值&安培; #xD; 
 2，name，value& #xD;< SOAPEnvelope> 
  

所以当我解析使用正则表达式查询替换为空字符串时，全文仍然在

现在我不熟悉编码，但这是SOAP消息的有效载荷。信封被剥离，这是ouputed到CSV文件。当我在Notepad ++中打开CSV时，新的行char似乎工作，但编码的值仍然存在。有没有人知道我失踪了？

我尝试添加（sb = Stringbuilder）

  sb.append（ <！[CDATA [）; 
 ... 
 sb.append（]]>）; 
  

但这似乎不起作用，JAXB似乎也逃避了这些字符。

 <？xml version =1.0encoding =UTF-8？>< soapenv：Envelope xmlns：soapenv =http ：//schemas.xmlsoap.org/soap/envelope/>< soapenv：Body>< ns4：ReportResult xmlns：ns2 =http://me.com/v1_9/servicexmlns：ns3 =http ：//me.com/v1_9/service/objectsxmlns：ns4 =http://me.com/v1_9/service/operations>& lt;！[CDATA [000000，LK20130930120048，Compant，Data， 20130930120048 ,,&安培; #xD; 
 000001，user，Fname，Mname，Lname，12345地址1，地址2222，setAddress3，setCity，OH，US，44332，N，N，E ,,,,,,,,,,,,,,,,,, 
 999999]]& gt< / ns4：ReportResult>< / soapenv：Body>< / soapenv：Envelope> 
  

另外我也会像这个，但是我使用默认的编组器为JAX-WS。

解决方案

JAXB（JSR-222）实现将执行以下操作： / p>

• \\\
将作为新行写入XML。 >
  
• \r 将被转义为& #xD;

演示代码

Foo

  import javax.xml.bind.annotation.XmlRootElement; 
 
 @XmlRootElement 
 public class Foo {
 
 public String slashN; 
 public String slashR; 
 public String slashRslashN; 
 
} 
  

演示

  import javax.xml.bind。*; 
 
 public class Demo {
 
 public static void main（String [] args）throws异常{
 JAXBContext jc = JAXBContext.newInstance（Foo.class）; 
 
 Foo foo = new Foo（）; 
 foo.slashN =Hello\\\
World; 
 foo.slashR =Hello\rWorld; 
 foo.slashRslashN =Hello\r\\\
World; 
 
 Marshaller marshaller = jc.createMarshaller（）; 
 marshaller.setProperty（Marshaller.JAXB_FORMATTED_OUTPUT，true）; 
 marshaller.marshal（foo，System.out）; 
} 
 
} 
  

输出

 <？xml version =1.0encoding =UTF-8standalone = ？ 是 > 
< foo> 
< slashN> Hello 
 World< / slashN> 
< slashR> Hello& #xD; World< / slashR> 
< slashRslashN> Hello& #xD; 
 World< / slashRslashN> 
< / foo> 
  

I have the following code...

public static final String NEWLINE = String.format("%n");
...
StringBuilder b = new StringBuilder();
...
b.append(NEWLINE);
return b.toString();

However when I run this in SOAPUI and look at the RAW it looks like it is augmenting it again and the new line turns into




So instead of

<SOAPEnvelope>1,name,value
             2,name,value<SOAPEnvelope>

It shows up as...

<SOAPEnvelope>1,name,value&#xD;
             2,name,value&#xD;<SOAPEnvelope>

So when I parse using a regex query to replace with an empty string the full text is still around

Now I am not as familiar with encoding but this is the payload of a SOAP message. The envelope is stripped away and this is ouputed to a CSV file. When I open the CSV in Notepad++ the new line char appears to work but that encoded value is still there. Does anyone know what I am missing?

I tried adding a (sb = Stringbuilder)

sb.append("<![CDATA[");
...
sb.append("]]>");

But this doesn't seem to work, again JAXB seems to escape the chars.

<?xml version="1.0" encoding="UTF-8"?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"><soapenv:Body><ns4:ReportResult xmlns:ns2="http://me.com/v1_9/service" xmlns:ns3="http://me.com/v1_9/service/objects" xmlns:ns4="http://me.com/v1_9/service/operations">&lt;![CDATA[000000,LK20130930120048,Compant,Data,20130930120048,,&#xD;
000001,user,Fname,Mname,Lname,12345 Address 1,Address 2222,setAddress3,setCity,OH,US,44332,,N,N,E,,,,?,,&#xD;
999999]]&gt;</ns4:ReportResult></soapenv:Body></soapenv:Envelope>

Also I would be fine with something like this but I use the default marshaller for JAX-WS. So I am not exactly sure where to put it.

解决方案

A JAXB (JSR-222) implementation will do the following:

• \n will be written to XML as a new line.
• \r will be escaped as 


Demo Code

Foo

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public class Foo {

    public String slashN;
    public String slashR;
    public String slashRslashN;

}

Demo

import javax.xml.bind.*;

public class Demo {

    public static void main(String[] args) throws Exception {
        JAXBContext jc = JAXBContext.newInstance(Foo.class);

        Foo foo = new Foo();
        foo.slashN = "Hello\nWorld";
        foo.slashR = "Hello\rWorld";
        foo.slashRslashN = "Hello\r\nWorld";

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(foo, System.out);
    }

}

Output

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<foo>
    <slashN>Hello
World</slashN>
    <slashR>Hello&#xD;World</slashR>
    <slashRslashN>Hello&#xD;
World</slashRslashN>
</foo>
