将字符串解析为 Java 对象

Question

我需要将这种格式的Strings 转换为对象的Array。

[{name=Nancy Chapman, email=nchapman0@comcast.net}, {name=Jimmy Fisher, email=jfisher1@photobucket.com}]

有什么简单的方法可以不用完全手动进行转换吗？

更新： 我从自定义 SQL 数据库 (Amazon Athena) 中提取这些值。并且自定义JDBC 不支持getArray()，所以看起来我需要手动解析包含Array 的Structs 的列。不幸的是，这是数据库的限制，我无法控制它。这是我在列上调用 getString() 时 SQL 数据库返回的格式。

SQL 表定义

 id (int)
 threadid (int)
 senderemail (string)
 sendername (string)
 subject (string)
 body (string)
 recipients (array<struct<name:string,email:string>>)
 ccrecipients (array<struct<name:string,email:string>>)
 bccrecipients (array<struct<name:string,email:string>>)
 attachments (array<binary>)
 date (timestamp)

Java 对象

MessageObj

public class MessageObj {

private int id;
private int threadId;
private String senderEmail;
private String senderName;
private String subject;
private String body;
private List<RecipientObj> recipients;
private List<RecipientObj> ccRecipients;
private List<RecipientObj> bccRecipients;
private List<File> attachments;
private Calendar date;
}

RecipientObj

public class RecipientObj {
private String email;
private String name;
}

解析数据。

ResultSet rs = statement.executeQuery(sql);

while (rs.next()) {
// Retrieve table column.
int id = rs.getInt("id");
Integer threadId = rs.getInt("threadid");
String senderEmail = rs.getString("senderemail");
String senderName = rs.getString("sendername");
String subject = rs.getString("subject");
String body = rs.getString("body");

//How to convert recipients into ArrayList? rs.getArray("recipients") not supported.
//... Code here to add into an ArrayList of MessageObj.
}

也许我误解了你的问题，但如果你稍微清理一下，你输入的内容应该可以工作，如下所示：

[{ name:"Nany Chapman", email:"nchapman0@comcast.net"}, 
{ name:"Nany Chapman", email:"nchapman0@comcast.net"}]

不要使用等号，而是使用冒号并在值周围加上引号。
