org.springframework.boot spring-boot-starter-cache net.sf.ehcache ehcache
创建ehcache.xml配置文件
修改springboot配置文件,引入ehcache.xml配置文件spring:
cache:
type: ehcache
ehcache:
config: classpath:ehcache/ehcache.xml
启用@EnableCaching
注解@SpringBootApplication
@EnableCaching
public class Application{public static void main(String[] args) {SpringApplication.run(Application.class, args);
}
}
实体类实现可序列化接口Serializable由于需要实体类支持缓存中的磁盘存储,所以需要实体类实现可序列化接口。
public class User implements Serializable{...
}
添加缓存注解@Cacheable
、@CacheEvict
@Cacheable
缓存数据@Service
public class UserServiceImpl implements UserService {@Autowired
private UserMapper userMapper;
@Override
@Cacheable(value="users")
public User selectUserById(int id) {User user=this.userMapper.selectUserById(id);
System.out.println("load data from db");
return user;
}
}
@CacheEvict
清除缓存@Service
public class UserServiceImpl implements UserService {@Autowired
private UserMapper userMapper;
@Override
@Cacheable(value="users")
public User selectUserById(int id) {User user=this.userMapper.selectUserById(id);
System.out.println("load data from db");
return user;
}
@CacheEvict(value="users", allEntries=true)
public void saveUsers(Users users) {this.userMapper.save(users);
}
@CacheEvict(value="users", allEntries=true)
public void deleteUserById(int id) {this.userMapper.deleteUserById(id);
}
}
其它
设置java.io.tmpdir
