JAX-RS请求自定义日期格式

如何在JAX-RS中使用JSON请求中的java.sql.Date或java.sql.Timestamp？

我在POST URL http://localhost:8080/jaxrs/webapi/students/上传递了请求，以将新学生添加到数据库中。创建的AT日期以yyyy-mm-dd格式传递。但是JAX-RS无法转换格式并初始化Student对象。添加请求样本，学生班级和学生资源

{
    "createdAt": "2018-45-05",
    "name": "Minne"
}

学生班

@XmlRootElement
public class Student {
    private long id;
    private String name;
    private Date createdAt;
....

创建学生资源方法

@Path("/students")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public class StudentRes {

    @POST
    public Student addStudent(Student student) {
        student.setId(students.size() + 1);
        students.put(student.getId(), stude
    }

我得到的错误是

您可以将其更改为private Date createdAt，而不是在Student POJO类中使用private String createdAt。现在，您可以使用一种将String类型的date转换为所需类型java.sql.Date的方法，如下所示：

public java.sql.Date convertToDate(String date)
{
        LocalDate localDate = LocalDate.parse(date);
        java.sql.Date sqlDate = java.sql.Date.valueOf(localDate);
        return sqlDate;
}
