所以我一直在遵循这个请求，将Redis集成到jhipster生成器上：https : //github.com/jhipster/generator- jhipster/pull/10057/commits/cd2f2865d35dfd77624dd3a38ed32822e895539d
这是我配置的：
ApplicationProperties.java：
package com.xxx.xxx.config; import org.springframework.boot.context.properties.ConfigurationProperties; import io.github.jhipster.config.JHipsterDefaults; /** * <p> * Properties are configured in the {@code application.yml} file. * See {@link io.github.jhipster.config.JHipsterProperties} for a good example. */ @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.ejs：
<%_ if (cacheProvider === 'redis') { _%> private final javax.cache.configuration.Configuration<Object, Object> jcacheConfiguration; public CacheConfiguration(JHipsterProperties jHipsterProperties, ApplicationProperties applicationProperties) { MutableConfiguration<Object, Object> jcacheConfig = new MutableConfiguration<>(); Config config = new Config(); config.useSingleServer() .setAddress(applicationProperties.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, applicationProperties.getRedis().getExpiration()))); jcacheConfiguration = RedissonConfiguration.fromInstance(Redisson.create(config), jcacheConfig); } <%_ if (enableHibernateCache) { _%> @Bean public HibernatePropertiesCustomizer hibernatePropertiesCustomizer(javax.cache.CacheManager cm) { return hibernateProperties -> hibernateProperties.put(ConfigSettings.CACHE_MANAGER, cm); } <%_ } _%> @Bean public JCacheManagerCustomizer cacheManagerCustomizer() { return cm -> { <%_ if (!skipUserManagement || (authenticationType === 'oauth2' && databaseType !== 'no')) { _%> createCache(cm, <%=packageName%>.repository<% if (reactive) { %>.reactive<% } %>.UserRepository.USERS_BY_LOGIN_CACHE); createCache(cm, <%=packageName%>.repository<% if (reactive) { %>.reactive<% } %>.UserRepository.USERS_BY_EMAIL_CACHE); <%_ if (enableHibernateCache) { _%> createCache(cm, <%=packageName%>.domain.<%= asEntity('User') %>.class.getName()); createCache(cm, <%=packageName%>.domain.Authority.class.getName()); createCache(cm, <%=packageName%>.domain.<%= asEntity('User') %>.class.getName() + ".authorities"); <%_ if (authenticationType === 'session') { _%> createCache(cm, <%=packageName%>.domain.PersistentToken.class.getName()); createCache(cm, <%=packageName%>.domain.<%= asEntity('User') %>.class.getName() + ".persistentTokens"); <%_ } _%> <%_ } _%> <%_ } _%> // jhipster-needle-redis-add-entry }; } private void createCache(javax.cache.CacheManager cm, String cacheName) { javax.cache.Cache<Object, Object> cache = cm.getCache(cacheName); if (cache != null) { cm.destroyCache(cacheName); } cm.createCache(cacheName, jcacheConfiguration); } <%_ } _%>
application.yml：
# =================================================================== # 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: # https://www.jhipster.tech/common-application-properties/ # =================================================================== application: application.redis.server: redis://localhost:6379 application.redis.expiration: 300
我的最后一个问题是在ApplicationProperties.java中，特别是：
private String server = JHipsterDefaults.Cache.Redis.server; private int expiration = JHipsterDefaults.Cache.Redis.expiration;
哪个状态：Redis无法解析或不是字段Java：
[ERROR] symbol: variable Redis [ERROR] location: interface io.github.jhipster.config.JHipsterDefaults.Cache
UPDATE ：解决了无效字段-解决方案：
private String server = "redis://localhost:6379"; private int expiration = 300;

最终更新：REDIS集成成功
redis-server ./mvnw
该消息显示是The elements [jhipster.cache.redis.expiration] were left unbound因为该属性在JhipsterProperties中不存在。您应该删除该值和配置application.redis.expiration，而不是
The elements [jhipster.cache.redis.expiration] were left unbound
application.redis.expiration
