Xml 模板:
@(product: models.Product, productComponents: List[models.ProductComponent])
<product>
<name>@product.name</name>
<tomcatLocation>@product.tomcatLocation</tomcatLocation>
<productComponents>
@for(productComponent <- productComponents) {
<component>
<name>@productComponent.name</name>
<packageName>@productComponent.packageName</packageName>
<buildPath>@productComponent.buildPath</buildPath>
<packageFormat>@productComponent.packageFormat</packageFormat>
<versionAction>@productComponent.versionAction</versionAction>
<versionFilePath>@productComponent.versionFilePath</versionFilePath>
<versionCommand>@productComponent.versionCommand</versionCommand>
</component>
}
</productComponents>
</product>
控制器动作:
public static Result upgradeProduct(String serverId, String productId) throws InterruptedException
{
models.Server server = models.Server.retrieveById(Long.parseLong(serverId));
models.Product product = models.Product.retrieveById(Long.parseLong(productId));
List<models.ProductComponent> productComponents =
models.ProductComponent.retrieveByProductId(Long.parseLong(productId));
Xml renderedXmlPage = upgradeService.render(product, productComponents);
Promise<WS.Response> upgradeStatus =
WS.url("http://" + server.hostIp + ":8085/upgradeProduct").setHeader("Content-Type", "text/xml").post(
renderedXmlPage.toString());
String testMessage = upgradeStatus.get().getBody();
return TODO;
}
网络服务:
public static Result upgradeProduct()
{
return async( WS.url(MAIN_URL).get().map(
new Function<WS.Response, Result>() {
public Result apply(WS.Response response)
{
try
{
Document doc = response.asXml();
return ok("I WORKED");
}
catch(RuntimeException e)
{
return ok("Error" + e.getMessage()+ "\n");
}
}
})
);
}
当我运行此操作时,会引发以下运行时异常
“Errorjava.lang.RuntimeException:org.xml.sax.SAXParseException;lineNumber:1;columnNumber:1;文件过早结束。”。
此异常在“Document doc = response.asXml();”处引发。我不知道为什么会出现这种情况?非常感谢任何帮助谢谢!
