Springboot (iii) integrated Redis

problems encountered

Springboot Integrated Redis, refer to the blog:

Http://www.tuicool.com/articles/mAriMbI

Problems that exist:
When injecting redistemplate, if you follow the blog's approach, add generics

@Autowired
Private redistemplate<string, user> redistemplate;

A startup error is generated:

Change to the following is no problem:

@Autowired
private Redistemplate redistemplate;

Integrate detailed procedures

The effect you actually write is as follows: adding MAVEN dependencies

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId> Spring-boot-starter-redis</artifactid>
</dependency>

Add a configuration file
Adding Redis server-side configuration to Application.properties

# Redis (redisproperties)
# Redis Database index (default = 0)
spring.redis.database=0  
# Redis server address
Spring.redis.host=localhost  
# Redis Server connection Port
spring.redis.port=6379  
# Redis Server connection password (default is empty)
spring.redis.password=  
# Connection pool Maximum number of connections (using negative values to indicate no limit)
spring.redis.pool.max-active=8  
# Connection pool Maximum blocking wait time (with negative values for No limit)
spring.redis.pool.max-wait=-1  
# The maximum idle connection in the connection pool
spring.redis.pool.max-idle=8  
# Minimum idle connection in connection pool
spring.redis.pool.min-idle=0  
# Connection time-out (ms)
spring.redis.timeout=0  

Test access in Controller

/** * * @version 1.0 * @Description * @Date 2016/10/15 18:30 * @Author NICK * * @RestController public class Hellocon

    Troller {@Autowired private stringredistemplate stringredistemplate;

    @Autowired private Redistemplate redistemplate; @RequestMapping ("/hello") public string Index () {//Save string Stringredistemplate.opsforvalue (). Set ("AAA"
        , "111");
        String string = Stringredistemplate.opsforvalue (). Get ("AAA");

        System.out.println (string);
        Save Object User user = New User ("Superman", 20);

        Redistemplate.opsforvalue (). Set (User.getusername (), user);
        user = new User ("Batman", 30);

        Redistemplate.opsforvalue (). Set (User.getusername (), user);
        user = new User ("Spider-Man", 40);
        Redistemplate.opsforvalue (). Set (User.getusername (), user);
        User User1 = (user) Redistemplate.opsforvalue (). Get ("Superman");
        System.out.println (User1.getage (). Longvalue ()); System.out.println ((User) RedistemplaTe.opsforvalue (). Get ("Batman")). Getage (). Longvalue ());

        System.out.println ((User) Redistemplate.opsforvalue (). Get ("Spider-Man")). Getage (). Longvalue ());
    Return "Hello World"; }
