使用设置为 Spring框架5.0.2.RELEASE Spring Security 5.0.0.RELEASE Hibernate 5.2.11.Final

我跟着spring boot＆amp; Vlad's link配置我的应用程序如下

db.properties - 

jdbc.driverClassName = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://hostname:port/appname?useSSL=false&serverTimezone=UTC&useLegacyDatetimeCode=false
jdbc.username = xxx
jdbc.password = xxx
jdbc.minPoolSize = 5
jdbc.maxPoolSize = 20
jdbc.maxIdleTime = 30000
hibernate.dialect = org.hibernate.dialect.MySQLDialect
hibernate.show_sql = true
hibernate.format_sql = false
spring.jpa.properties.hibernate.jdbc.time_zone = UTC

HibernateConfig.java 

@Configuration
@EnableTransactionManagement
@ComponentScan(basePackages="in.greenstack.ikon")
@PropertySource(value = { "classpath:/resources/db.properties" })
public class HibernateConfig {

    @Autowired
    private Environment environment;

    @Bean(name = "myDataSource")
    ....

    @Bean
    public LocalSessionFactoryBean sessionFactory() {
        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setDataSource(dataSource());
        sessionFactory.setPackagesToScan(new String[] { "in.greenstack.ikon.entity" });
        sessionFactory.setHibernateProperties(hibernateProperties());
        return sessionFactory;
     }

    private Properties hibernateProperties() {
        Properties properties = new Properties();
        properties.put("hibernate.dialect", environment.getRequiredProperty("hibernate.dialect"));
        properties.put("hibernate.show_sql", environment.getRequiredProperty("hibernate.show_sql"));
        properties.put("hibernate.format_sql", environment.getRequiredProperty("hibernate.format_sql"));
        properties.put("spring.jpa.properties.hibernate.jdbc.time_zone", 
                environment.getRequiredProperty("spring.jpa.properties.hibernate.jdbc.time_zone"));
        return properties;        
   }

实体 - 

@Entity
@Table(name = "PROJECT_MASTER")
public class Project {

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "ID")
private int id;

@Column(name = "NAME")
private String name;

@Column(name = "START_DATE")
private Date startDate;

@Column(name = "END_DATE")
private Date endDate;

@ManyToOne
@JoinColumn(name = "FINANCIAL_YEAR")
private FinancialYear financialYear;

表定义 - 

    CREATE TABLE `PROJECT_MASTER` (
    `ID` int(11) NOT NULL AUTO_INCREMENT,
  `NAME` varchar(50) NOT NULL,
  `FINANCIAL_YEAR` varchar(20) DEFAULT NULL,
  `START_DATE` date DEFAULT NULL,
  `END_DATE` date DEFAULT NULL,

从上面的日志中可以看出，绑定参数是从客户端发送的正确值（2017年4月1日和2018年3月31日），但在db中保存时仍然保存不正确的日期。

请提出我错过的建议。

试试这个（它对我有用）。在spring boot主应用程序文件中写下以下代码片段。

@PostConstruct
public void started() {
    TimeZone.setDefault(TimeZone.getTimeZone("UTC"));
}

改变这个：

 properties.put("spring.jpa.properties.hibernate.jdbc.time_zone", 
                environment.getRequiredProperty("spring.jpa.properties.hibernate.jdbc.time_zone"));

到此：

 properties.put("hibernate.jdbc.time_zone", 
            environment.getRequiredProperty("spring.jpa.properties.hibernate.jdbc.time_zone"));

答案 2 :(得分：1)

我认为您应该将spring.jpa.properties.hibernate.jdbc.time_zone = UTC放在application.yml或application.properties的{​​{1}} / main/中，而不要放在test/中。而且，我认为db.properties优先于.properties。如果我错了，请纠正我。

而且，此时区配置也受到.yml的影响。

查看此信息：https://aboullaite.me/spring-boot-time-zone-configuration-using-hibernate/

而且，正如我测试的那样，我看到如果您要保存一个本身没有时区信息的Timezone.getDefault()（仅在其java.util.Date属性中为true）和该列定义不保留时区信息，此属性将影响保存到数据库的值，但是不会，当您从数据库中检索行时，该属性不会起作用。后者仅受Calendar影响。同时，如果您设置Timezone.getDefault()，则已保存和已检索值都是您想要的时区。

因此，如果您保存和查询同一应用程序中的信息，则此属性可能不是操纵Date值的最合适方法。只需使用Timezone.getDefault()。
