我正在尝试使用JAVA Web服务与SQL Server数据库进行通信。在我部署和测试Web服务之后，我尝试了一些方法，但没有任何更改反映在数据库中。例如：
@WebMethod(operationName = "readPerson")
public String readPerson(@WebParam(name = "ID") long id)
{
String s = null;
try {
String connectionUrl= "jdbc:sqlserver://localhost:1433;" +
"databaseName=myDatabase;user=sa;password=password;";
con = DriverManager.getConnection(connectionUrl);
Statement myStmt = con.createStatement();
String query = "SELECT * FROM People WHERE ID=" + id;
ResultSet rs = myStmt.executeQuery(query);
String name = null;
String surname = null;
int age = 0;
long contact = 0;
String location= null;
while(rs.next())
{
name = rs.getString("Name");
surname = rs.getString("Surname");
age = rs.getInt("Age");
contact = rs.getLong("Contact");
location = rs.getString("Location");
}
s =
"ID: " + Long.toString(id)
+ "\nName: " + name
+ "\nSurname: " + surname
+ "\nAge: " + Integer.toString(age)
+ "\nContact: " + Long.toString(contact)
+ "\nLocation: " + location;
} catch (SQLException ex) {
Logger.getLogger(JavaService.class.getName()).log(Level.SEVERE, null, ex);
}
return s;
}
当我调用web方法时：
readPerson Method invocation
Method parameter(s)
Type Value
long 1001
Method returned
java.lang.String : "null"
SOAP Request
<?xml version="1.0" encoding="UTF-8"?>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
<S:Header/>
<S:Body>
<ns2:readPerson xmlns:ns2="http://javaservice/">
<ID>1001</ID>
</ns2:readPerson>
</S:Body>
</S:Envelope>
SOAP Response
<?xml version="1.0" encoding="UTF-8"?>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
<S:Body>
<ns2:readPersonResponse xmlns:ns2="http://javaservice/"/>
</S:Body>
</S:Envelope>
这个方法应该在我的“People”表中返回一个带有记录字段内容的字符串，但是当我测试它时，没有任何反应。也没有错误。奇怪的是，当我在普通应用程序（不是Web服务）中尝试此方法时，它可以工作。有什么想法吗？
