Spring Frameworks

Spring framework legacy 시스템 redis 연동 예제

Overviews

스프링 부트로 되어 있는 예제는 많으나 레거시로된 spring framework 프로젝트의 연동 예제는 찾기가 힘들었습니다. 

기존 코드에 설정을 추가했는데 에러가 발생해서 별도 프로젝트로 먼저 구성해 보고 삽입 하기로 했습니다. 

 

프로젝트 생성 

이클립스에서 프로젝트 생성

  • 프로젝트 선택
  • Spring - Spring Legacy Project 선택 
  • Simple Projects - Simple Spring Web Maven 선택 

기본 프로젝트를 생성 후 필요한 코드를 추가해서 테스트.

 

개발환경

  • spring framework 4.3.9
  • jdk 1.8
  • maven
  • eclipse

Dependency

redis 연동 dependency

* spring-data-redis 2.*는 spring framework 5.* 이상에서만 가능합니다. 

		<dependency>
			<groupId>org.springframework.data</groupId>
			<artifactId>spring-data-redis</artifactId>
			<version>1.8.23.RELEASE</version>
		</dependency>

		<dependency>
			<groupId>redis.clients</groupId>
			<artifactId>jedis</artifactId>
			<version>2.10.2</version>
		</dependency>

RestController에 필요한 dependency

* 간단한 프로젝트를 만들고 캐시에 객체를 바인딩 할 때 기본 프로젝트에 필요한 라이브러리입니다.  

		<dependency>
			<groupId>com.fasterxml.jackson.core</groupId>
			<artifactId>jackson-core</artifactId>
			<version>2.10.1</version>
		</dependency>

		<dependency>

테스트를 위한 서비스 생성 

Controller 

@RestController
public class TestController {

    @Autowired
    private TestCacheService testCacheService;
    
    @RequestMapping("/test")
    public List<User> getUsers() {//Welcome page, non-rest
        return testCacheService.getUsers();
    }

    @RequestMapping("/test-refresh")
    public List<User> refreshUsers() {//Welcome page, non-rest
        testCacheService.removeCacheUsers();
        return testCacheService.getUsers();
    }
}

 

Service

@Service
public class TestCacheService {

    @Cacheable(cacheNames="userCache")
    public List<User> getUsers(){
        List<User> users = new ArrayList<>();
        users.add(new User("고객1", 21));
        users.add(new User("고객2", 22));
        users.add(new User("고객3", 23));
        return users;
    }

    @Caching(evict = {
            @CacheEvict(cacheNames="userCache", allEntries = true)
        })
    public void removeCacheUsers(){
    }
    
}

 

Domain

public class User implements Serializable{

    private static final long serialVersionUID = 1L;

    private String id;
    private int age;
    private Timestamp timestamp;
    
    public User(String id, int age) {

    }

    @Override
    public int hashCode() {
        final int prime = 31;
        int result = 1;
        result = prime * result + ((id == null) ? 0 : id.hashCode());
        return result;
    }

    @Override
    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (obj == null)
            return false;

        } else if (!id.equals(other.id))
            return false;
        return true;
    }
    
}

 

도메인 클래스와 서비스에 대한 내용은 이전 글을 참고 하시면 될거 같습니다.
