java - hibernate.jdbc.time_zone = 忽略 UTC

Question

使用设置为

• Spring 框架 5.0.2.RELEASE
• Spring Security 5.0.0.RELEASE
• hibernate 5.2.11.Final

我关注了spring boot & Vlad's link如下配置我的应用程序

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,

从上面的日志可以看出，绑定(bind)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)，但是在数据库中保存时它仍然保存不正确的日期。

请指教我遗漏的地方。

试试这个(对我有用)。在您的 spring boot 主应用程序文件中写入以下代码片段。

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