[求助] @ConditionalOnClass @ConditionalOnBean 导致 starter 配置未生效

@EnableConfigurationProperties(XXXXElasticSearchProperties.class) @ConditionalOnProperty(value = "xxxxx.es.enabled", havingValue = "true") @ConditionalOnClass(RestHighLevelClient.class) @ConditionalOnBean(RestHighLevelClient.class) public class LogAutoConfig { @Bean(name = "restHighLevelClient") public RestHighLevelClient restHighLevelClient() { // 拆分地址 YidianElasticSearchProperties.Rest rest = yidianElasticSearchProperties.getRest(); final boolean credentials = rest == null || StringUtils.isEmpty(rest.getPassword()) || StringUtils.isEmpty(rest.getUsername()); // 权限验证 CredentialsProvider credentialsProvider = new BasicCredentialsProvider(); if (!credentials) { // 配置权限验证 credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(rest.getUsername(), rest.getPassword())); } // 转换成 HttpHost 数组 HttpHost[] httpHost = yidianElasticSearchProperties.getUris().stream().map(HttpHost::create).toArray(HttpHost[]::new); // 构建连接对象 RestClientBuilder builder = RestClient.builder( httpHost); // 异步连接延时配置 builder.setRequestConfigCallback(requestConfigBuilder -> { requestConfigBuilder.setConnectTimeout(yidianElasticSearchProperties.getConnectTimeout()); requestConfigBuilder.setSocketTimeout(yidianElasticSearchProperties.getSocketTimeout()); requestConfigBuilder .setConnectionRequestTimeout(yidianElasticSearchProperties.getConnectionRequestTimeout()); return requestConfigBuilder; }); // 异步连接数配置 builder.setHttpClientConfigCallback( httpClientBuilder -> { httpClientBuilder.setMaxConnTotal(yidianElasticSearchProperties.getMaxConnectNum()); httpClientBuilder.setMaxConnPerRoute(yidianElasticSearchProperties.getMaxConnectPerRoute()); if (credentials) { httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider); } return httpClientBuilder; }); return new RestHighLevelClient(builder); } } 

这个配置在自定义的 starer 里面,启动时这个类有被扫描到但是不符合 math 所以没有被装配。

然后我手动复制一份这个类命名为 LogAutoConfig1，并删除了 @ConditionalOnClass @ConditionalOnBean 等一系列条件装配注解，神奇的是这个它居然报错 restHighLevelClient define in starter xxx path 说是在 starter 中 define 了,这就很奇怪了之前不是都没有装配，这下为什么会提示 define 了,于是我删除了 LogAutoConfig1 中的 restHighLevelClient 这部分代码，至此代码成功注册到 spring。

这是为什么？
