spring-security包缓存内存与redis共存 sprintboot使用spring-security包,缓存内存与redis共存方式

项目修改需求描述

项目需要使用分布式缓存机制，但是使用@Cacheable原始仅配置了内存版的，故此次需要改成redis用以支持多应用模式的。

项目中如果直接改成redis的，存在一个问题。如果内存对象同一类，比如都是String的list对象,存的key值又都是"code"，会把缓存给冲掉，所以需要对redis的做后缀处理。又因为只有一个redis服务器，所以需要对缓存做项目的前缀处理。

还希望能支持历史项目，做到内存与redis共存，所以顺便就做了CacheManager处理。

代码处理

首先如果希望程序支持缓存需要注解

@EnableCaching

然后在application.yml里增加redis的配置

spring:
  application:
    name:app
  redis:
    database: 0
    host: XX.XX.XX.XX
    port: 6379
    password:
    pool:
      max-total: 100
      block-when-exhausted: false
    timeout: 5000  

增加一个redis处理类RedisConfig，此处做了redis前缀的处理

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cache.concurrent.ConcurrentMapCacheManager;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.core.env.Environment;
import org.springframework.data.redis.cache.RedisCacheConfiguration;
import org.springframework.data.redis.cache.RedisCacheManager;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.RedisSerializationContext;

import org.springframework.data.redis.serializer.StringRedisSerializer;
import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;

@Configuration
public class RedisConfig {	
    @Autowired  
    private Environment env;  

    @Bean
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        // 为了开发方便，一般使用<String, Object>
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);

        // Json序列化配置
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(objectMapper);        
        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();

        // 设置key的序列化方式
        redisTemplate.setKeySerializer(stringRedisSerializer);
        // 设置hashkey的序列化方式
        redisTemplate.setHashKeySerializer(stringRedisSerializer);
        // 设置value的序列化方式
//        template.setValueSerializer(stringRedisSerializer);
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        // 设置hashvalue的序列化方式
//        template.setHashValueSerializer(stringRedisSerializer);
        redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);        
//        template.setBeanClassLoader(this.getClass().getClassLoader());
//        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }
    @Bean("redisCacheManager")
    //@Primary
    public RedisCacheManager myRedisCacheManager(RedisConnectionFactory redisConnectionFactory){
        RedisSerializer<String> redisSerializer = new StringRedisSerializer();

        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(om);     
        String prefixStr = env.getProperty("spring.application.name") + ":";
        if(!'prod'.equals(env.getActiveProfiles()[0])) {
        	prefixStr += env.getActiveProfiles()[0]  + ":";
        }
        
        // 配置序列化（解决乱码的问题）
//        RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig(this.getClass().getClassLoader())
        RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig()
//        		.computePrefixWith(cacheName -> env.getProperty("spring.application.name").concat(":")
//        				.concat(env.getActiveProfiles()[0])
//        				.concat(":")
//        				.concat(cacheName))
        		.prefixKeysWith(prefixStr)
                .serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(redisSerializer))
                .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(jackson2JsonRedisSerializer))
                .disableCachingNullValues();

        RedisCacheManager cacheManager = RedisCacheManager.builder(redisConnectionFactory).cacheDefaults(config).build();
        return cacheManager;
    }

    @Bean("defaultCacheManager")
    @Primary
    public ConcurrentMapCacheManager cacheManager() {
    	ConcurrentMapCacheManager cacheManager = new ConcurrentMapCacheManager();
		return cacheManager;
	}	
}

注：RedisCacheManager 和 RedisTemplate 里的json处理要注意一致性。

这边配置了2个cacheManager：（ConcurrentMapCacheManager 默认缓存、RedisCacheManager redis缓存）

必须要默认一个cacheManager，哪个是默认的就在哪个bean上加注解@Primary

如果不写会报下列错误：

增加MyKeyGenerator，做redis后缀处理

CachingConfigurerSupport 这个接口默认就有@Primary功能，无需额外配置

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.cache.annotation.CacheEvict;
import org.springframework.cache.annotation.Cacheable;
import org.springframework.cache.annotation.CachingConfigurerSupport;
import org.springframework.cache.interceptor.KeyGenerator;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import java.lang.reflect.Method;

@Configuration
public class MyKeyGeneratorConfig extends CachingConfigurerSupport {
	private final Logger logger = LoggerFactory.getLogger(this.getClass());	
    @Bean
//    @Primary
//    @Override
    public KeyGenerator myKeyGenerator() {
        return new KeyGenerator() {
            @Override
            public Object generate(Object target, Method method, Object... params) {
//                String re= String.format("%s::%s(%s)",target.getClass().getName(),method.getName(),
//                        CollectionUtils.arrayToList(params));//Arrays.asList(params)
            	
        		StringBuilder sb = new StringBuilder();
        		String valueStr = null;
        		if (method.isAnnotationPresent(Cacheable.class)) {
        			Cacheable ca = method.getAnnotation(Cacheable.class);
        			if (ca.value() != null) {
        				valueStr = ca.value()[0];
        			}
        		} else if(method.isAnnotationPresent(CacheEvict.class)) {
        			CacheEvict ce = method.getAnnotation(CacheEvict.class);
        			if (ce.value() != null) {
        				valueStr = ce.value()[0];
        			}
        		}
        		
        		if (valueStr != null) {
        			sb.append(valueStr + ":");
        		} else {
        			sb.append(target.getClass().getName() + ":");
        			sb.append(method.getName() + ":");
        		}
        		for (Object obj : params) {
        			sb.append(obj.toString() + ":");
        		}
//        		return sb.toString();
        		String re = sb.toString();
            	
            	
                logger.debug("缓存生成的key:{}。",re);
                return re;
            }
        };
    }	
}

缓存类处理：

 @Cacheable(value = "XXX", keyGenerator = "myKeyGenerator", cacheManager = "redisCacheManager")
 public List<String> getXXXX(String userCode) {
  XXXXXXXXXX
 }

对应的@CacheEvict 记得也把该属性加上，如果不是默认的话： keyGenerator = “myKeyGenerator”

权限类处理：

针对权限类controller增加注解判断，没权限直接报错

@PreAuthorize(“hasAuthority(‘privileges')”)

权限缓存加载类：

 @Cacheable("privileges")
 private List<GrantedAuthority> makeAuth(String userCode) {
  List<MyGrantedAuthority> privileges = XXX;
  return privileges;
 }

权限类：

import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.SpringSecurityCoreVersion;
import org.springframework.util.Assert;
public class MyGrantedAuthority  implements GrantedAuthority {
	private static final long serialVersionUID = SpringSecurityCoreVersion.SERIAL_VERSION_UID;
	private String authority;	
    public MyGrantedAuthority() {
    	super();
    }

	public MyGrantedAuthority(String authority) {
		Assert.hasText(authority, "A granted authority textual representation is required");
		this.authority = authority;
	}

	@Override
	public String getAuthority() {
		return authority;
	}

	@Override
	public boolean equals(Object obj) {
		if (this == obj) {
			return true;
		}

		if (obj instanceof MyGrantedAuthority) {
			return authority.equals(((MyGrantedAuthority) obj).authority);
		}

		return false;
	}

	@Override
	public int hashCode() {
		return this.authority.hashCode();
	}

	@Override
	public String toString() {
		return this.authority;
	}
}

异常问题解决

如果项目中存在LocalDateTime会报错：

需要对类里面的LocalDateTime增加注解

import com.fasterxml.jackson.databind.annotation.JsonDeserialize;
import com.fasterxml.jackson.databind.annotation.JsonSerialize;
import com.fasterxml.jackson.datatype.jsr310.deser.LocalDateTimeDeserializer;
import com.fasterxml.jackson.datatype.jsr310.ser.LocalDateTimeSerializer;

    @JsonSerialize(using = LocalDateTimeSerializer.class)
    @JsonDeserialize(using = LocalDateTimeDeserializer.class)
 private LocalDateTime XXX;

如不存在jsr310的包可以增加pom配置

  <!-- 缓存、权限 -->
        <dependency>
            <groupId>com.fasterxml.jackson.datatype</groupId>
            <artifactId>jackson-datatype-jsr310</artifactId>
            <version>2.9.8</version>
        </dependency>

UserDetails子类代码

import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
//import com.fasterxml.jackson.annotation.JsonIgnore;
public class JwtUser implements UserDetails {
	private String username;
	private String userCode;
	private String password;
	private Collection<? extends GrantedAuthority> authorities;
	private Boolean enabled;
	private Boolean accountNonExpired = true;
	private Boolean accountNonLocked = true;
	private Boolean credentialsNonExpired = true;	
	public JwtUser() {
		super();
	}
	String getPassword();
	...
	...
	...
}

这边需要写一个无参数构造函数，因为json反序列化原因

UserDetails 这个里面对应getXXX（例如getPassword）的对象都要写对应的参数，否则json转义的时候会报错，如果用不到就增加注解@JsonIgnore。

权限类异常

使用SimpleGrantedAuthority会因无参数构造函数报错，因为json反序列化原因，需要重新建一个子类，并且增加无参数构造函数，类名为MyGrantedAuthority（此类上面详细代码已写，故不重复写了）。
