@Scheduled 没有将我的 JSON 值更新为 FALSE

Question

我试图在 1:00 下午将我的 H2 银行的一列的所有值设置为 false，但我在这样做时遇到困难，消息正在控制台上打印，但是票数保持为真。

我的 table 看起来像这样，我希望每天 1:00PM 的 VOTED 字段的值为 FALSE

ID	EMAIL	PASSWORD	NAME	VOTED
1	bruno@gmail.com	a$j1Eic8Okp.IczSVQbU.ru.s.dXoxd1fdzWtK2os9oE9y9ZO8wvMx6	Bruno	TRUE
2	james@gmail.com	a$F/KLm5ULaNRVEL/K6MMeveZXr770G5cI3S7HZnEw.b7TZDENkCWBC	James	TRUE
3	robert@gmail.com	a$uHZjSrroGBtRBB/V.norRuOcDVz42MXnm0/2yLPGpE3P5XtPRo7L6	Robert	FALSE

这是我在 UserServices.java

中使用的逻辑

尽管项目运行，用户在 @Scheduled

中确定的时间后仍然为 TRUE

@Scheduled(cron = "0 00 13* * *")
    public void resetVotes() throws InterruptedException {
            
    List<User> userArray = repository.findAll();
    for(User user: userArray ) {
        user.setVoted(false);
    }
}

这是我在@Scheduled

中确定的时间到达时在控制台上收到的消息

Hibernate: 
    select
        user0_.id as id1_1_,
        user0_.email as email2_1_,
        user0_.password as password3_1_,
        user0_.name as name4_1_,
        user0_.voted as voted5_1_ 
    from
        db_users user0_

这是我在项目中使用的类：

User.java

package com.dbserver.restaurantes.entities;

@Table(name = "db_users")
public class User {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(name = "Name")
    private String username;
    private String email;
    private String password;
    private Boolean voted = false;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getUsername() {
        return username;
    }

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

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getPassword() {
        return password;
    }

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

    public Boolean getVoted() {
        return voted;
    }

    public void setVoted(Boolean voted) {
        this.voted = voted;
    }

}

UserDTO.java

package com.dbserver.restaurantes.dto;

import com.dbserver.restaurantes.entities.User;

public class UserDTO {
    private Long id;
    private String username;
    private String email;
    private String password;
    private Boolean voted = false;

    public UserDTO() {
    }

    public UserDTO(Long id, String username, String email, String password, Boolean voted) {
        this.id = id;
        this.username = username;
        this.email = email;
        this.password = password;
        this.voted = voted;
    }

    public UserDTO(User user) {
        id = user.getId();
        username = user.getUsername();
        email = user.getEmail();
        password = user.getPassword();
        voted = user.getVoted();
    }

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getUsername() {
        return username;
    }

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

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getPassword() {
        return password;
    }

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

    public Boolean getVoted() {
        return voted;
    }

    public void setVoted(Boolean voted) {
        this.voted = voted;
    }

Answer 1

我认为您需要 re-update setVoted(false)

之后的用户列表

@Scheduled(cron = "0 00 13* * *")
public void resetVotes() throws InterruptedException {
            
    List<User> userArray = repository.findAll();
    for(User user: userArray ) {
        user.setVoted(false);
    }

    repository.save(userArray);
}

Answer 2

您不需要从数据库加载所有用户。

您可以通过自定义查询更新数据。

   @Scheduled(cron = "0 00 13* * *")
    public void resetVotes() throws InterruptedException {
                
        repository.resetVotes();
    }

UserRepository.java

package com.dbserver.restaurantes.repositories;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import com.dbserver.restaurantes.entities.User;

public interface UserRepository extends JpaRepository<User, Long> {

User findByEmail(String email);

//update custom query 
@Modifying
@Query("update User set voted=false ")
int resetVotes();

}
