我是 Jax-Rs 的新手。我尝试将数据从 html 发布到 Webresource 方法。在运行时我遇到异常,即
exception
javax.servlet.ServletException: com.sun.jersey.api.container.ContainerException: Exception injecting parameters to Web resource method
com.sun.jersey.spi.container.servlet.WebComponent.service(WebComponent.java:310)
com.sun.jersey.spi.container.servlet.ServletContainer.service(ServletContainer.java:314)

com.sun.jersey.server.impl.model.method.dispatch.FormDispatchProvider$FormParamInjectable.getValue(FormDispatchProvider.java:233)
我提到了下面的 Html 页面和 Web 资源方法:-
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Test Jax-RS Object</title>
</head>
<body>
<form action="services/fruitstore/loadObject1" method="POST" >
<table>
<tr>
<td>ID:</td>
<td><input type="text" name="id"></td>
</tr>
<tr>
<td>Name:</td>
<td><input type="text" name="name"></td>
</tr>
<tr>
<td><input type="submit" Value="Submit"></td>
</tr>
</table>
</form>
</body>
</html>
网络资源方法:-
@POST
@Path("loadObject1")
@Consumes("application/x-www-form-urlencoded")
public void loadObject1(@FormParam("id") String id,@FormParam("name") String name){
System.out.println("====================");
System.out.println("Fruit ID"+id+" Name"+name);
}
请帮我?
