使用Redis进行Spring Boot缓存，密钥为\ xac \ xed \ x00 \ x05t \ x00 \ x06 [英] Spring boot caching with redis,key have \xac\xed\x00\x05t\x00\x06

问题描述

我想使用Spring cache @Cacheable来管理缓存.而真正的缓存是redis.

I want to use Spring cache @Cacheable to manager cache. And the real cache is redis.

我的代码如下:

@PostMapping("/post")
@CachePut(value = "abc", key = "#key")
public String putInRedis(@RequestParam String key, @RequestParam String value) {
    saveInDB(key, value);

    return value;
}

@GetMapping("/get")
@Cacheable(value = "abc", key = "#key")
public String queryRedis(@RequestParam String key) {

    return findByKey(key);
}

收到发帖请求后

localhost:8080/post?key = key& value = value

localhost:8080/post?key=key&value=value

redis服务器出现一个奇怪的密钥

the redis server appear a weird key

127.0.0.1:6379> keys *
1) "abc:\xac\xed\x00\x05t\x00\x03key"
127.0.0.1:6379> GET "abc:\xac\xed\x00\x05t\x00\x03key"
"\xac\xed\x00\x05t\x00\x05value"

如何将@Cacheable的Serializer设置为StringRedisTemplate默认值:

how to set @Cacheable's Serializer like StringRedisTemplate default：

public StringRedisTemplate() {
    RedisSerializer<String> stringSerializer = new StringRedisSerializer();
    setKeySerializer(stringSerializer);
    setValueSerializer(stringSerializer);
    setHashKeySerializer(stringSerializer);
    setHashValueSerializer(stringSerializer);
}

我的application.properties:

my application.properties:

spring.redis.host=localhost
spring.redis.password=
spring.redis.port=6379

build.gradle

build.gradle

group 'io.freezhan'
version '1.0-SNAPSHOT'

buildscript {
    repositories {
        maven {
            url 'https://plugins.gradle.org/m2/'
        }
    }
    dependencies {
        classpath 'org.springframework.boot:spring-boot-gradle-plugin:1.4.0.RELEASE'
    }
}

task wrapper(type: Wrapper) {
    gradleVersion = '2.13'
    distributionUrl = "https://services.gradle.org/distributions/gradle-$gradleVersion-all.zip"
}

apply plugin: 'java'
apply plugin: 'spring-boot'

sourceCompatibility = 1.5

repositories {
    mavenCentral()
}

dependencies {
    compile("org.springframework.boot:spring-boot-starter-web") {
        exclude module: "spring-boot-starter-tomcat"
    }
    compile("org.springframework.boot:spring-boot-starter-data-redis")
    compile("org.springframework.boot:spring-boot-starter-jetty")
    compile("org.springframework.boot:spring-boot-starter-actuator")
    compile 'org.projectlombok:lombok:1.16.10'
    testCompile("junit:junit")
}

推荐答案

Spring的缓存功能允许使用不同的缓存实现.Redis是其中之一.可以与 RedisCacheManager 类一起使用.

The caching - feature of Spring allows to use different cache - implementations. One of them is Redis. It can be used with the class RedisCacheManager. The Spring documentation says:

如果Redis可用并已配置，则会自动配置 RedisCacheManager .

这是我建议影响Redis的方法-缓存-集成:

This is the approach that I propose to influence the Redis - caching - integration:

1. 将 RedisCacheManager 定义为自己的bean.

1. Define the RedisCacheManager as bean on your own.

将 RedisTemplate 传递给 RedisCacheManager 的构造函数.

我找到了一个示例为此，可以使用编程配置在Internet上进行.还有一个使用基于XML的配置的示例.

I found an example for this on the Internet using a programmmatic configuration. There is also an example using XML-based configuration.
