JHipster Redis集成元素未绑定错误

Question

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) {

application.yml：

# ===================================================================

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;

Answer 1

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
