spring-data-jpa 问题汇总

时间类型和 数据库默认时间处理，entity 配置如下

import java.util.Date;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;
import javax.persistence.Column;
@Temporal(TemporalType.TIMESTAMP)
    @Basic(optional = false)
    @Column(name = "SignUpTime", insertable= false)
    private Date signUpTime;

自定义 pageable 

final PageRequest page1 = new PageRequest(
  0, 20, Direction.ASC, "lastName", "salary"
);

final PageRequest page2 = new PageRequest(
  0, 20, new Sort(
    new Order(Direction.ASC, "lastName"), 
    new Order(Direction.DESC, "salary")
  )
);
