SpringBoot 构建 REST 服务

摘要

该文章只为了说明如何整合REST服务，并不介绍如何使用，当做笔记吧。

MongoDB

以MongoDB为例

maven 依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-rest</artifactId>
</dependency>

properties配置

spring.data.mongodb.host=127.0.0.1
spring.data.mongodb.authentication-database=admin
spring.data.mongodb.username=johnson
spring.data.mongodb.password=123456
spring.data.mongodb.port=27017
spring.data.mongodb.database=mydatabase

实体类

public class Book {
    private Integer id;
    private String name;
    private String author;
    public Integer getId() {return id;}
    public void setId(Integer id) { this.id = id; }
    public String getName() { return name; }
    public void setName(String name) { this.name = name; }
    public String getAuthor() { return author; }
    public void setAuthor(String author) { this.author = author; }
}

接口类

public interface BookDao extends MongoRepository<Book, Integer> {}

测试

启动项目后浏览器打开http://localhost:8080/,可以看到如下信息：

{
  "_links" : {
    "books" : {
      "href" : "http://localhost:8080/books{?page,size,sort}",
      "templated" : true
    },
    "profile" : {
      "href" : "http://localhost:8080/profile"
    }
  }
}

可以输入http://localhost:8080/books，即可看到返回Book的分页数据。
