模板内容

<?xml version=\"1.0\" encoding=\"UTF-8\"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV=\"http://schemas.xmlsoap.org/soap/envelope/\" 
xmlns:SOAP-ENC=\"http://schemas.xmlsoap.org/soap/encoding/\" 
xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" 
xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" 
xmlns:gw=\"urn:gwService\">
    <SOAP-ENV:Body SOAP-ENV:encodingStyle=\"http://schemas.xmlsoap.org/soap/encoding/\">
        <gw:ldtpExchStatusQuery>
            <transId>${transId}</transId>
        </SOAP-ENV:Body>
    </SOAP-ENV:Envelope>

具体使用

//设置数据
Map dataMap = new HashMap<>();
dataMap.put("transId","abc");
//设置版本号
Version version = new Version("2.3.28");
Configuration configuration = new Configuration(version);  
configuration.setDefaultEncoding("utf-8");  
//模板文件路径
configuration.setDirectoryForTemplateLoading(new File("D:\freemarker.xml"));

Template template = configuration.getTemplate("freemarker.xml");  
ByteArrayOutputStream out = new ByteArrayOutputStream();
Writer w = new OutputStreamWriter(out, "utf-8");
 //将数据写入模板
template.process(dataMap, w);
w.close(); 
byte[] bytes = out.toByteArray();
out.close();
MultipartFile file = new MockMultipartFile(ContentType.APPLICATION_OCTET_STREAM.toString(), bytes);//得到最终模板
