将Redis集成到JHipster CacheConfiguration错误 [英] Integrate Redis to JHipster CacheConfiguration error
问题描述
在Github上执行以下拉取请求后，我正在尝试将Redis缓存集成到JHipster生成器: https://github.com/jhipster/generator-jhipster/pull/10057/commits/cd2f2865d35dfd77624dd3a38ed32822e895539d#
I'm trying to integrate redis cache to JHipster generator following this pull request on Github: https://github.com/jhipster/generator-jhipster/pull/10057/commits/cd2f2865d35dfd77624dd3a38ed32822e895539d#
我在构建项目时收到此错误:
I receive this error while building my project:
[ERROR] symbol: method getRedis()
[ERROR] location: class io.github.jhipster.config.JHipsterProperties.Cache
[ERROR] ../config/CacheConfiguration.java:[61,139] cannot find symbol
JHipsterProperties.CacheJava(67108964)类型的getRedis()方法未定义
The method getRedis() is undefined for the type JHipsterProperties.CacheJava(67108964)
在哪里定义了getRedis()?
Where is getRedis() defined?
CacheConfiguration方法:
CacheConfiguration method in CacheConfiguration.java:
private final javax.cache.configuration.Configuration<Object, Object> jcacheConfiguration;
public CacheConfiguration(JHipsterProperties jHipsterProperties) {
MutableConfiguration<Object, Object> jcacheConfig = new MutableConfiguration<>();
Config config = new Config();
config.useSingleServer()
.setAddress(jHipsterProperties.getCache().getRedis().getServer())
.setSubscriptionConnectionMinimumIdleSize(1)
.setSubscriptionConnectionPoolSize(50)
.setConnectionMinimumIdleSize(24)
.setConnectionPoolSize(64)
.setDnsMonitoringInterval(5000)
.setIdleConnectionTimeout(10000)
.setConnectTimeout(10000)
.setTimeout(3000)
.setRetryAttempts(3)
.setRetryInterval(1500)
.setDatabase(0)
.setPassword(null)
.setSubscriptionsPerConnection(5)
.setClientName(null)
.setSslEnableEndpointIdentification(true)
.setSslProvider(SslProvider.JDK)
.setSslTruststore(null)
.setSslTruststorePassword(null)
.setSslKeystore(null)
.setSslKeystorePassword(null)
.setPingConnectionInterval(0)
.setKeepAlive(false)
.setTcpNoDelay(false);
jcacheConfig.setStatisticsEnabled(true);
jcacheConfig.setExpiryPolicyFactory(CreatedExpiryPolicy.factoryOf(new Duration(TimeUnit.SECONDS, jHipsterProperties.getCache().getRedis().getExpiration())));
jcacheConfiguration = RedissonConfiguration.fromInstance(Redisson.create(config), jcacheConfig);
}
我是否缺少getRedis()的某些依赖项?
Am I missing some dependencies for getRedis()?
注意:我在build.gradle.ejs中忽略了这个；这会导致问题吗?
Note: I left out this in build.gradle.ejs; would this be causing the problem?
<%_ if (cacheProvider === 'redis') { _%>
implementation "org.redisson:redisson"
<%_ if (enableHibernateCache) { _%>
implementation "org.hibernate:hibernate-jcache"
<%_ } _%>
<%_ } _%>
解决方案?:
ApplicationProperties.java:
ApplicationProperties.java:
@ConfigurationProperties(prefix = "application", ignoreUnknownFields = false)
public class ApplicationProperties {
private final Redis redis = new Redis();
public Redis getRedis() {
return redis;
}
public static class Redis {
private String server = JHipsterDefaults.Cache.Redis.server;
private int expiration = JHipsterDefaults.Cache.Redis.expiration;
public String getServer() {
return server;
}
public void setServer(String server) {
this.server = server;
}
public int getExpiration() {
return expiration;
}
public void setExpiration(int expiration) {
this.expiration = expiration;
}
}
}
CacheConfiguration.java
CacheConfiguration.java
<%_ if (cacheProvider === 'redis') { _%>

public CacheConfiguration(JHipsterProperties jHipsterProperties, ApplicationProperties applicationProperties) {

config.useSingleServer()

# ===================================================================
# Application specific properties
# Add your own application properties here, see the ApplicationProperties class
# to have type-safe configuration, like in the JHipsterProperties above

# More documentation is available at:

application.redis.expiration: 300
推荐答案
You are missing the respective changes in the JHipster library which are not released yet (located in this pull request).
My advice (until it's released) would be to copy the changes (the Redis class and values) from JhipsterProperties.java to your ApplicationProperties.java.
Then if you need to configure the values to a non-default value, you can do so in your application.yml under the application: key.
最后将ApplicationProperties applicationProperties添加到JhipsterProperties旁边的CacheConfiguration.java中的构造函数中，并从那里引用getRedis().
Lastly add ApplicationProperties applicationProperties to the constructor in CacheConfiguration.java next to JhipsterProperties and reference getRedis() from there.
我相信reddison依赖项也是必需的.
I believe the reddison dependency is also needed.
