Question

我正在获取JSON字符串数据，如下所示

{"username":"KU"，"password":"KU"}。

如何将此字符串转换为JAXBElement对象。

请回答我。

您可以使用Jackson轻松地对JSON进行解组。请参阅下面的代码，了解上面用户名和密码的大小写。它将以下内容输出到控制台控制台，表明它已经从JSON字符串创建了该类的一个实例。

{"username":"KU","password":"KU"} -> Username [KU], Password [KU]。

import org.codehaus.jackson.map.ObjectMapper;

public class JaxbTest {
  public static void main(String[] args) throws Throwable {
    String json = "{\"username\":\"KU\",\"password\":\"KU\"}";
    ObjectMapper mapper = new ObjectMapper();
    JavaObject javaObject = mapper.readValue(json, JavaObject.class);

    System.out.println(json + " -> " + javaObject.toString());
  }

  private static class JavaObject {
    private String username;
    private String password;

    public JavaObject() { }

    public String getUsername() {
      return username;
    }

    public void setUsername(String username) {
      this.username = username;
    }

    public String getPassword() {
      return password;
    }

    public void setPassword(String password) {
      this.password = password;
    }

    @Override
    public String toString() {
      return "Username [" + this.username + "], Password [" + this.password + "]";
    }
  }
}
