Spring Boot + Spring Data JPA + Java 8 date et heure (JSR310)
Dans l'application JPA Spring Boot + Spring Data, pour prendre en charge les API JSR310java.time.*, nous devons enregistrer ceJsr310JpaConverters manuellement.
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.data.jpa.convert.threeten.Jsr310JpaConverters;
@EntityScan(
basePackageClasses = {Application.class, Jsr310JpaConverters.class}
)
@SpringBootApplication
public class Application {
//...
}
P.S Tested with Spring Boot 1.5.1.RELEASE, Spring Data JPA 1.11.0.RELEASE
1. Exemple complet
1.1 A model contains a java.time.LocalDate field.
package com.example.model;
import javax.persistence.*;
import java.time.LocalDate;
@Entity
public class Customer {
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "CUST_SEQ")
@SequenceGenerator(sequenceName = "customer_seq", allocationSize = 1, name = "CUST_SEQ")
Long id;
String name;
@Column(name = "CREATED_DATE")
LocalDate date;
//...
1.2 @EntityScan to scan and register Jsr310JpaConverters like this :
package com.example;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.data.jpa.convert.threeten.Jsr310JpaConverters;
import java.util.Arrays;
//for jsr310 java 8 java.time.*
@EntityScan(
basePackageClasses = {Application.class, Jsr310JpaConverters.class}
)
@SpringBootApplication
public class Application {
public static void main(String[] args) throws Exception {
SpringApplication.run(Application.class, args);
}
@Bean
public CommandLineRunner run(ApplicationContext appContext) {
return args -> {
System.out.println("hello World!");
};
}
}
