Using set up as
- Spring framework 5.0.2.RELEASE
- Spring Security 5.0.0.RELEASE
- Hibernate 5.2.11.Final
I followed spring boot & Vlad's link to configure my application as below
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;
}
Entity -
@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;
Table Definition -
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,

As can be seen from above logs, that the binding parameter is the correct value (1st April 2017 & 31st March 2018) sent from client, but when saving in db it is still saving incorrect dates.
Kindly advice what I have missed.

回答1:
Try this(it worked for me). Write below code snippet in your spring boot main application file.
@PostConstruct
public void started() {
TimeZone.setDefault(TimeZone.getTimeZone("UTC"));
}

Change this:
properties.put("spring.jpa.properties.hibernate.jdbc.time_zone",
environment.getRequiredProperty("spring.jpa.properties.hibernate.jdbc.time_zone"));
to this:
properties.put("hibernate.jdbc.time_zone",
environment.getRequiredProperty("spring.jpa.properties.hibernate.jdbc.time_zone"));

I think you should put spring.jpa.properties.hibernate.jdbc.time_zone = UTC in application.yml/application.properties of main/ or test/, not in db.properties. And, I think .properties takes precedence over .yml. Correct me if I am wrong.
And, this timezone config is also affected by Timezone.getDefault().
See this post: https://aboullaite.me/spring-boot-time-zone-configuration-using-hibernate/
And, as I test, I see that if you want to save a java.util.Date, which has no timezone info in itself(only in its Calendar property, this is true), and the column definition hold no place for timezone info, this property will affect the value saved to DB, but not that when you retrieve the row from DB; the latter is affected only by Timezone.getDefault(). Meanwhile, if you set Timezone.getDefault(), the saved and retrieved value will both be the timezone you want.
So, this property may not be the most proper way to manipulate the value of Date, if you save and query for the information in the same application. Just use Timezone.setDefault(Timezone.getTimezone("XXX")).
