我试图在我的Jersey实现资源类中检索对象的集合,如下所示:
@POST
@Path("/send")
@Consumes({ MediaType.APPLICATION_JSON })
@Produces({ MediaType.APPLICATION_JSON })
public String sendEmails(ArrayList<AnyEmail> email) {
//emailManager.sendEmail(email);
return "success";
}
我有@XmlRootElement上面的'AnyEmail.
但是,当我使用REST客户端工具发布时:
emails : [
{"body": "Testing the web service", "header": "Hi", "footer": "<br/>test"},
{"body": "Testing the web service", "header": "Hi", "footer": "<br/>test"}
]
我明白了:
<html><head><title>Apache Tomcat/7.0.22 - Error report</title><style><!--H1 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:22px;} H2 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:16px;} H3 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:14px;} BODY {font-family:Tahoma,Arial,sans-serif;color:black;background-color:white;} B {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;} P {font-family:Tahoma,Arial,sans-serif;background:white;color:black;font-size:12px;}A {color : black;}A.name {color : black;}HR {color : #525D76;}--></style> </head><body><h1>HTTP Status 500 - </h1><HR size="1" noshade="noshade"><p><b>type</b> Exception report</p><p><b>message</b> <u></u></p><p><b>description</b> <u>The server encountered an internal error () that prevented it from fulfilling this request.</u></p><p><b>exception</b> <pre>javax.servlet.ServletException: Servlet execution threw an exception

现在我试过:
"emails" : [
{"body": "Testing the web service", "header": "Hi", "footer": "<br/>test"},
{"body": "Testing the web service", "header": "Hi", "footer": "<br/>test"}
]
我得到:
SEVERE: Servlet.service() for servlet [Jersey Web Application] in context with path [/API] threw exception
java.lang.ArrayIndexOutOfBoundsException: -1
at java.util.ArrayList.get(ArrayList.java:324)
at com.sun.jersey.json.impl.reader.JsonXmlStreamReader.valueRead(JsonXmlStreamReader.java:165)
at com.sun.jersey.json.impl.reader.JsonXmlStreamReader.readNext(JsonXmlStreamReader.java:330)

为什么不使用简单的Java数组???
[
{"body": "Testing the web service", "header": "Hi", "footer": "<br/>test"},
{"body": "Testing the web service", "header": "Hi", "footer": "<br/>test"}
]
然后是以下方法:
@POST
@Path("/send")
@Consumes({ MediaType.APPLICATION_JSON })
@Produces({ MediaType.APPLICATION_JSON })
public String sendEmails(AnyEmail[] emails) {
//emailManager.sendEmail(emails);
return "success";
}
这应该够了吧...
这是应该起作用的：
{
"anyEmail" : [
{"body": "Testing the web service", "header": "Hi", "footer": "<br/>test"},
{"body": "Testing the web service", "header": "Hi", "footer": "<br/>test"}
]
}
另外，您可能想使用 POJO 方法，这是 JSON 的首选方法 - 请参阅此处：https: //jersey.java.net/documentation/1.18/json.html
基于 JAXB 的 JSON 支持在某些边缘情况下存在各种问题，因为 XML（JAXB 的设计目的）和 JSON 之间不存在 1:1 映射。
