spring boot 整合redis

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

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

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@Indexedprivate String firstname;@Indexedprivate String lastname;private Address address;private List<Family>familyList;public Person() {    }public Person(String firstname, String lastname) {this.firstname = firstname;this.lastname = lastname;}//补充get set toString}

public class Address {@Indexedprivate String city;@Indexedprivate String country;public Address() {}public Address(String city, String country) {this.city = city;this.country = country;}//补充get set toString}

public class Family {@Indexedprivate String type;@Indexedprivate 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：

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

 只要继承CrudRepository即可，如下：

public interface PersonRepository extends CrudRepository<Person, String> {List<Person> findByLastname(String lastname);Page<Person> findPersonByLastname(String lastname, Pageable page);List<Person> findByFirstnameAndLastname(String firstname, String lastname);List<Person> findByAddress_City(String city);List<Person> 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 {@Autowiredprivate PersonRepository repository;@Testpublic 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List<Family>list =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);}@Testpublic void selectPerson() {List<Person>list = repository.findByAddress_City("北京");System.out.println(list);}@Testpublic void updatePerson() {Person person = repository.findByFirstnameAndLastname("张","有才").get(0);person.setLastname("小明");Person update = repository.save(person);System.out.println(update);}@Testpublic void deletePerson() {Person person = repository.findByFirstnameAndLastname("张","小明").get(0);repository.delete(person);}}
