Spring Boot入门样例-310-mongodb整合mongodb数据库

Mongodb是一款高性能内存Nosql数据库，支持对键值的查询。本demo演示如何演示如何mongodb缓存数据并读取。

前言

本Spring Boot入门样例准备工作参考：

Spring Boot入门样例-001-Java和Maven安装配置Spring Boot入门样例-003-idea 安装配置和插件Spring Boot入门样例-005-如何运行

pox.xml

必要的依赖如下，具体参见该项目的pox.xml

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-mongodb</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency>

配置文件

resources/application.yml配置内容

spring: # mongodb data: mongodb: uri: mongodb://127.0.0.1:27017/spring-boot-demo-db

代码解析

StudentDao.java StudentDao继承MongoRepository<Student, String>

@Component public interface StudentDao extends MongoRepository<Student, String> { public List<Student> findByName(String name); public List<Student> findByAge(Integer type); }

StudentController.java 如下 @CachePut 和 @Cacheable都会将数据缓存到Redis中

@RestController @RequestMapping("/student") public class StudentController { @Autowired StudentDao studentDao; @GetMapping("/view/{id}") public String view(HttpServletRequest request, @PathVariable String id) { List<Student> models = studentDao.findByName(id); return "ok " + models.toString(); } @GetMapping("/add/{name}/{age}") public String add(HttpServletRequest request, @PathVariable String name, @PathVariable Integer age) { Student model = new Student(); model.setName(name); model.setAge(age); studentDao.save(model); return "ok"; } }

运行

点击运行

浏览器访问 http://localhost:8080/student/add/funson/30 ok 浏览器访问 http://localhost:8080/student/view/funson [Student(id=381213910235222016, name=funson, age=30)]
