#SPRING BOOT:Hibernate实现的JPA中使用joda-time
`joda-time`在java8出现之前很长时间作为Java中处理日期时间的事实标准，但是想要在JPA实体类中使用joda-time需要做以下配置
##dependencies
在`pom.xml`文件中添加

```
<dependency>
	<groupId>joda-time</groupId>
	<artifactId>joda-time</artifactId>
</dependency>
<dependency>
	<groupId>org.jadira.usertype</groupId>
	<artifactId>usertype.extended</artifactId>
	<version>5.0.0.GA</version>
</dependency>
```
##application.properties
在`src/main/resources/application.properties`配置文件中添加

```
spring.jpa.properties.jadira.usertype.autoRegisterUserTypes = true

```
##JPA实体类

```
// 映射为 DATETIME 类型字段 (MySQL)
private DateTime createTime;

// 映射为 DATE 类型字段 (MySQL)
private LocalDate birthdayDate;
```

##绑定json数据
在`pom.xml`中添加

```
<dependency>
  <groupId>com.fasterxml.jackson.datatype</groupId>
  <artifactId>jackson-datatype-joda</artifactId>
</dependency>
```
在controller中接收json请求

```
@RequestMapping("/add")
@ResponseBody
public User addUser(@RequestBody User user) {
 // ....
}
```
发送一个Content-Type为application/json的请求, addUser方法将接收一个User实例

```
{"createTime":"1970-01-01T00:00:00","birthdayDate":"1970-01-01"}
```
