工具:idea

环境:jdk1.8

1、环境配置

在ieda中新建maven工程,导入依赖

    <artifactId>slf4j-api</artifactId>

2、配置文件

在main下面新建资源文件夹resources.在resources下新建spring配置文件spring.xml文件

            <bean class="org.springframework.data.redis.serializer.StringRedisSerializer"></bean>
        </property>
    </bean>
</beans>

在resources下新建log4j配置文件log4j.properties

这个配置文件基本通用,可以不用改,直接拷过去就能用了

# Global logging configuration
log4j.rootLogger=DEBUG, stdout
# Console output...
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

3、启动项目

然后我们借助spring的测试环境测试

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:spring.xml"})
public class TestSpringDataRedis {
    @Resource(name = "redisTemplate")
    private ValueOperations<String,Object> valueOperations;
    @Test
    public void test(){
//        valueOperations.set("a","123");
        System.out.println(valueOperations.get("a"));
    }
}
