    @Override
    public int getSize() {
        Long size = redisTemplate.execute(new RedisCallback() {
            @Override
            public Long doInRedis(RedisConnection connection)
                    throws DataAccessException {
                return connection.dbSize();
            }
        });
        return size.intValue();
    }
}

5、springmvc.xml



    
    
    
    

    
    
    
    
    

    
    
    
    

    
    
        
        
        
        
    

    
        
            
                i18n
            
        
    
    
    
        
    

    
        
        
        
        
        
        
    

    
    
    
    


    
    
        
    
    
        
    

    
        
            
                
                    unauthorized

创建BaseTestCase，并在该类上加上两个注解

@RunWith(SpringJUnit4ClassRunner.class)

@ContextConfiguration(locations={"classpath:applicationContext.xml"})

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:applicationContext.xml"})
public class BaseTestCase

public class UserServiceImplTest extends BaseTestCase {
    @Autowired
    private UserService userService;

    @Test
    public void getRolesByUserId() {
        Set rolesByUserId = userService.getRolesByUserId(1);
        for (String s : rolesByUserId) {
            System.out.println(s);
        }
    }
