1. 配置數(shù)據(jù)源

spring:
  data:
    mongodb:
      collection: msgDetails
      uri: mongodb://tester01:tester01@127.0.0.1:27016/test

2. pom 添加依賴包

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

3. 注入工具類

@Autowired
    private  MongoTemplate mongoTemplate;

4. 增刪改查

Test
    public void saveTest() {
        mongoTemplate.save(person);
    }

    @Test
    public void findTest() {
        Person p = mongoTemplate.findOne(query(where("name").is("Joe")), Person.class);
        System.out.println(p);
    }

    @Test
    public void updateTest() {
        mongoTemplate.updateFirst(query(where("name").is("Joe")), update("age", 35), Person.class);
        Person p = mongoTemplate.findOne(query(where("name").is("Joe")), Person.class);
        System.out.println(p);
    }

    @Test
    public void removeTest() {
        List<Person> people =  mongoTemplate.findAll(Person.class);
        System.out.println(people.size());

        Person p = mongoTemplate.findOne(query(where("name").is("Joe")), Person.class);
        mongoTemplate.remove(p);

        people =  mongoTemplate.findAll(Person.class);
        System.out.println(people.size());

        mongoTemplate.dropCollection(Person.class);
    }
