java - Spring mongo 和 Joda DateTime

Question

将 Long 转换为 Joda DateTime 时出现此异常。

org.springframework.core.convert.ConverterNotFoundException:
    No converter found capable of converting from type java.lang.Long
    to type org.joda.time.DateTime

我正在使用

        artifactId>spring-core</artifactId>
        <version>4.0.3.RELEASE</version>

        <artifactId>spring-integration-core</artifactId>
        <version>4.0.3.RELEASE</version>

        <artifactId>spring-integration-mongodb</artifactId>

        <artifactId>spring-integration-xml</artifactId>
        <version>4.0.3.RELEASE</version>

        <artifactId>json-path</artifactId>
        <version>0.9.1</version>

        <artifactId>spring-data-commons-core</artifactId>
        <version>1.4.0.RELEASE</version>

        <artifactId>spring-data-commons</artifactId>
        <version>1.8.1.RELEASE</version>

有谁知道我还需要什么才能将 Long 转换为 DateTime？

谢谢

尝试 DateTime(长即时)路线。如果需要格式化，请尝试将 long 转换为 String，然后使用 DateTimeFormatter:

import org.joda.time.DateTime;
import org.joda.time.format.DateTimeFormat;
import org.joda.time.format.DateTimeFormatter;

    long abc;  //assign some value to this long
    String s = String.valueOf(abc);  //convert long to string
    DateTimeFormatter formatter = DateTimeFormat.forPattern("yyyy-MM-dd HH:mm:ss.S");  ///modify this according to your needs    
    DateTime dt = formatter.parseDateTime(date);
