spring boot 整合redis

1.在pom文件中添加spring-boot-starter-data-redis依赖启动器

    org.springframework.boot
    spring-boot-starter-data-redis

2.编写三个实体类

@RedisHash("persons")  // 指定操作实体类对象在Redis数据库中的存储空间
public class Person {

    @Id// 标识实体类主键
    private String id;
    // 标识对应属性在Redis数据库中生成二级索引,索引名就是属性名，可以方便地进行数据条件查询
    @Indexed
    private String firstname;
    @Indexed
    private String lastname;
    private Address address;
    private ListfamilyList;

    public Person() {    }

    public Person(String firstname, String lastname) {

        this.firstname = firstname;
        this.lastname = lastname;

    }

//补充get set toString

}

public class Address {

    @Indexed
    private String city;
    @Indexed
    private String country;

    public Address() {

    }

    public Address(String city, String country) {

        this.city = city;
        this.country = country;

    }

    //补充get set toString

}

public class Family {

    @Indexed
    private String type;

    @Indexed
    private String username;

    public Family() {    }

    public Family(String type, String username) {

        this.type = type;
        this.username = username;

    }

   //补充get set toString

}

3.编写Repository接口

不需要添加spring-boot-starter-data-jpa这个依赖，即：

    org.springframework.boot
    spring-boot-starter-data-jpa

 只要继承CrudRepository即可，如下：

public interface PersonRepository extends CrudRepository {

    List findByLastname(String lastname);

    Page findPersonByLastname(String lastname, Pageable page);

    List findByFirstnameAndLastname(String firstname, String lastname);

    List findByAddress_City(String city);

    List findByFamilyList_Username(String username);

}

4.在全局配置文件application.properties中添加Redis数据库连接配置

# Redis服务器地址
spring.redis.host=127.0.0.1

# Redis服务器连接端口
spring.redis.port=6379

# Redis服务器连接密码（默认为空）
spring.redis.password=

5.编写单元测试进行接口方法测试以及整合测试

@SpringBootTest
public class RedisTests {

    @Autowired
    private PersonRepository repository;

    @Test
    public void savePerson() {

        Person person =new Person("张","有才");
        Person person2 =new Person("James","Harden");

        // 创建并添加住址信息
        Address address=new Address("北京","China");
        person.setAddress(address);

        // 创建并添加家庭成员
        Listlist =new ArrayList<>();
        Family dad =new Family("父亲","张良");
        Family mom =new Family("母亲","李香君");
        list.add(dad);
        list.add(mom);
        person.setFamilyList(list);

        // 向Redis数据库添加数据
        Person save = repository.save(person);
        Person save2 = repository.save(person2);
        System.out.println(save);
        System.out.println(save2);

    }

    @Test
    public void selectPerson() {

        Listlist = repository.findByAddress_City("北京");
        System.out.println(list);

    }

    @Test
    public void updatePerson() {

        Person person = repository.findByFirstnameAndLastname("张","有才").get(0);
        person.setLastname("小明");
        Person update = repository.save(person);
        System.out.println(update);

    }

    @Test
    public void deletePerson() {

        Person person = repository.findByFirstnameAndLastname("张","小明").get(0);
        repository.delete(person);

    }

}
