JHipster Redis集成元素未绑定错误 [英] JHipster Redis Integration element unbound error
本文介绍了JHipster Redis集成元素未绑定错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
因此，我一直遵循以下请求，将redis集成到jhipster生成器中:
So I've been following this pull request to integrate redis onto jhipster generator: https://github.com/jhipster/generator-jhipster/pull/10057/commits/cd2f2865d35dfd77624dd3a38ed32822e895539d
这是我配置的:
ApplicationProperties.java:
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:
CacheConfiguration.java.ejs:

config.useSingleServer()

application:
application.redis.server: redis://localhost:6379
application.redis.expiration: 300
我的最后一个问题是在ApplicationProperties.java中，具体是:
My final problem is in ApplicationProperties.java, specifically:
private String server = JHipsterDefaults.Cache.Redis.server;
private int expiration = JHipsterDefaults.Cache.Redis.expiration;
其中指出:Redis无法解析或不是字段Java:
which states: Redis cannot be resolved or is not a fieldJava:
[ERROR] symbol: variable Redis
[ERROR] location: interface io.github.jhipster.config.JHipsterDefaults.Cache
更新:解决了无效字段-解决方案:
UPDATE: invalid field resolved-- Solution:
private String server = "redis://localhost:6379";
private int expiration = 300;

推荐答案
该消息显示The elements [jhipster.cache.redis.expiration] were left unbound，因为该属性在JhipsterProperties中不存在.您应该删除该值并配置application.redis.expiration
The message says The elements [jhipster.cache.redis.expiration] were left unbound because that property does not exist in JhipsterProperties. You should remove that value and configure application.redis.expiration instead
