Spring与Spring 1.4.0的集成。获取误差

Question

我从Spring 1.2.3升级到1.4.0，并附带了用于Spring集成的依赖项，即4.3.1

我正在发送JSON内容，但在请求提交时会出现错误。以前，它在Spring 1.2.3和spring集成4.1.2中运行良好。

Answer 1

Spring 1.2.3不支持WebService (SOAP)。现在我们有WebServicesAutoConfiguration，从1.4.0开始。在这里您可以找到以下代码：

String path = this.properties.getPath();
String urlMapping = (path.endsWith("/") ? path + "*" : path + "/*");
ServletRegistrationBean registration = new ServletRegistrationBean(servlet,
            urlMapping);

在WebServicesProperties中遇到意外的默认设置

@NotNull
@Pattern(regexp = "/[^?#]*", message = "Path must start with /")
private String path = "/services";

因此，新创建的MessageDispatcherServlet拦截所有请求，因为您希望在path="/services/test"上得到它们。

如果您对应用程序中的SOAP服务器端不感兴趣，可以将WebServicesAutoConfiguration排除在自动配置之外。

否则，请考虑更改您的服务URL或为spring.webservices.path应用程序属性指定其他内容。
