What is the Spring Data REST
Spring Data REST is on the Spring Data repository based repository can be automatically output as REST resources, currently supports Spring Data JPA, Spring Data MongoDB, Spring Data Neo4j, Spring Data GemFire, Spring Data Cassandra's repository is automatically converted into a REST service. Note that automatic. Simply put, Spring Data REST our need to write a lot of templates REST interface to automate done.
Real
1: New Spring Boot item, and adding a dependency JPA Rest Repositories, and import database-driven
2: configuration properties
application.properties
//数据源
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/book
spring.datasource.username=root
spring.datasource.password=123456
//JPA
spring.jpa.hibernate.ddl-auto=update
spring.jpa.show-sql=true
spring.jackson.serialization.indent-output=true
Person entity class
@Entity
public class Person {
@Id
@GeneratedValue
private Long id;
private String name;
private Integer age;
private String address;
public Person() {
super();
}
public Person(Long id, String name, Integer age, String address) {
super();
this.id = id;
this.name = name;
this.age = age;
this.address = address;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
}
Entity classes Repository
public interface PersonRepository extends JpaRepository<Person, Long> {
Person findByNameStartsWith(String name);
}

REST service test
list:
Gets a single object (object id get 1)
Query:
above custom entity classes Repository defined findByNameStartsWith method, this method if you want to be exposed as REST resources, need to be modified as follows:
//Spring Data REST默认规则是在实体类之后加上"s"来形成路径，我们可以通过@RepositoryRestResource注解的path属性进行修改！
@RepositoryRestResource(path = "people")
public interface PersonRepository extends JpaRepository<Person, Long> {
@RestResource(path = "nameStartsWith", rel = "nameStartsWith")
Person findByNameStartsWith(@Param("name")String name);
}

Save:
As can be seen by output, after successfully saved, id our new data is 45;
Update (update just added data id 45):
Delete (delete the data just added id 45):
At this point then GET access data id 45: the
show REST resource being accessed does not exist;
custom made
Custom root path:
In the example above, the path of our REST resources are accessed in the root directory, ie http: // localhost: 8080 / people , if we need to customize the root words, just under application.properties you can add the following definition:
spring.data.rest.base-path=/api
At this point the path REST resources becomes http: // localhost: 8080 / api / people;
custom node path:
the Spring the Data REST default rule is to add "s" after the entity classes to form a path, we can @RepositoryRestResource comment the path attribute modification!
The default is http: // localhost: 8080 / persons
@RepositoryRestResource(path = "people")
At this point the path REST resources becomes http: // localhost: 8080 / people;
