在Spring Security OAuth2中,缓存的处理可以使用Jackson进行序列化。具体实现步骤如下:
1. 添加Jackson依赖
在pom.xml文件中添加以下依赖:
```xml
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
</dependency>
```
2. 实现序列化器
创建一个自定义的序列化器,继承自`JsonSerializer`:
```java
public class OAuth2AccessTokenSerializer extends JsonSerializer<OAuth2AccessToken> {
@Override
public void serialize(OAuth2AccessToken token, JsonGenerator gen, SerializerProvider serializers)
throws IOException, JsonProcessingException {
gen.writeStartObject();
gen.writeStringField("value", token.getValue());
gen.writeNumberField("expiration", token.getExpiration().getTime());
// 其他字段序列化
gen.writeEndObject();
}
}
```
3. 注册序列化器
在配置类中注册序列化器:
```java
@Configuration
public class JacksonConfiguration {
@Bean
public ObjectMapper objectMapper() {
ObjectMapper objectMapper = new ObjectMapper();
SimpleModule module = new SimpleModule();
module.addSerializer(OAuth2AccessToken.class, new OAuth2AccessTokenSerializer());
objectMapper.registerModule(module);
return objectMapper;
}
}
```
4. 配置缓存
在缓存配置类中,指定序列化器:
```java
@Configuration
@EnableCaching
public class CacheConfiguration extends CachingConfigurerSupport {
@Autowired
private ObjectMapper objectMapper;
@Bean
public CacheManager cacheManager(RedisConnectionFactory connectionFactory) {
RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig()
.serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(new Jackson2JsonRedisSerializer<>(OAuth2AccessToken.class, objectMapper)));
return RedisCacheManager.builder(connectionFactory)
.cacheDefaults(config)
.build();
}
}
```
这样就可以使用Jackson进行缓存的序列化了。
