如何在 Spring Boot 中禁用个人健康指标？

Question

我需要为单个数据源禁用 Spring 启动运行状况指示器（我们有很多，我不想全部禁用它们或为其他数据源创建指示器，如果可能的话）。

我采取的路径是扩展 DataSourceHealthContributorAutoConfiguration。 我知道这曾经在 DataSourceHealthIndicatorAutoConfiguration 发挥作用时起作用，但现在它是一个子接口，它没有按预期工作。

预期：不会检查使用 Snowflake 驱动程序的数据源的运行状况指示器

现实：数据源似乎在启动时被过滤掉了，但是，仍然为所有数据源调用 createIndicator。

如果需要更多信息，请告诉我。 这是我第一次尝试更改 java 代码，所以我可能会遗漏一些东西。

package com.org.database.snowflake.config;

import com.zaxxer.hikari.HikariDataSource;
import javax.sql.DataSource;
import org.springframework.beans.factory.ObjectProvider;
import org.springframework.boot.jdbc.metadata.DataSourcePoolMetadataProvider;
import org.springframework.context.annotation.Configuration;
import org.springframework.boot.actuate.autoconfigure.jdbc.DataSourceHealthContributorAutoConfiguration;
import java.util.Map;
import java.util.stream.Collectors;

@Configuration
public class ExcludeSnowflakeHealthIndicatorConfig extends DataSourceHealthContributorAutoConfiguration {

    public ExcludeSnowflakeHealthIndicatorConfig(Map<String, DataSource> dataSources, ObjectProvider<DataSourcePoolMetadataProvider> metadataProviders) {
        // Filter out data sources that use the Snowflake Driver
        super(filterDataSources(dataSources), metadataProviders);
    }

    private static Map<String, DataSource> filterDataSources(Map<String, DataSource> dataSources) {
        return dataSources.entrySet().stream()
                .filter(dataSourceEntry -> {
                    if (dataSourceEntry.getValue() instanceof HikariDataSource) {
                        HikariDataSource hikariDataSource = (HikariDataSource) dataSourceEntry.getValue();
                        return !hikariDataSource.getDriverClassName().equals("net.snowflake.client.jdbc.SnowflakeDriver");
                    } else {
                        return true;
                    }
                }).collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue));
    }
}

这似乎有效：

package com.org.database.snowflake.config;

import com.zaxxer.hikari.HikariDataSource;
import javax.sql.DataSource;
import org.springframework.beans.factory.ObjectProvider;
import org.springframework.boot.actuate.health.HealthContributor;
import org.springframework.boot.jdbc.metadata.DataSourcePoolMetadataProvider;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.boot.actuate.autoconfigure.jdbc.DataSourceHealthContributorAutoConfiguration;
import java.util.Map;
import java.util.stream.Collectors;

@Configuration
public class ExcludeSnowflakeHealthIndicatorConfig extends DataSourceHealthContributorAutoConfiguration {
    private final Map<String, DataSource> ds;

    public ExcludeSnowflakeHealthIndicatorConfig(Map<String, DataSource> dataSources, ObjectProvider<DataSourcePoolMetadataProvider> metadataProviders) {
        // Filter out data sources that use the Snowflake Driver
        super(filterDataSources(dataSources), metadataProviders);
        this.ds = filterDataSources(dataSources);
    }

    private static Map<String, DataSource> filterDataSources(Map<String, DataSource> dataSources) {
        return dataSources.entrySet().stream()
                .filter(dataSourceEntry -> {
                    if (dataSourceEntry.getValue() instanceof HikariDataSource) {
                        HikariDataSource hikariDataSource = (HikariDataSource) dataSourceEntry.getValue();
                        return !hikariDataSource.getDriverClassName().equals("net.snowflake.client.jdbc.SnowflakeDriver");
                    } else {
                        return true;
                    }
                }).collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue));
    }

    @Bean
    public HealthContributor dbHealthContributor(Map<String, DataSource> dataSources) {
        return super.dbHealthContributor(ds);
    }
}
