springboot集成 shardingjdbc 启动报错

SQLFeatureNotSupportedException: isValid

研究半天,看了shardingjdbc官网GitHub,也发现了这个问题:
https://github.com/apache/shardingsphere/pull/6002/files/c191c9571ab5a2e9e6d3f0c0f84c8bb6cd36d851

然后特别记录一下: 解决方案:

package com.spark.fqdemoshardingsphere.config;

import org.springframework.beans.factory.ObjectProvider;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.actuate.autoconfigure.jdbc.DataSourceHealthContributorAutoConfiguration;

import org.springframework.boot.actuate.jdbc.DataSourceHealthIndicator;
import org.springframework.boot.jdbc.metadata.DataSourcePoolMetadataProvider;
import org.springframework.context.annotation.Configuration;
import org.springframework.util.StringUtils;

import javax.sql.DataSource;
import java.util.Map;

@Configuration
public class DataSourceHealthConfig extends DataSourceHealthContributorAutoConfiguration {

    @Value("${spring.datasource.dbcp2.validation-query:select 1}")
    private String defaultQuery;


    public DataSourceHealthConfig(Map<String, DataSource> dataSources, ObjectProvider<DataSourcePoolMetadataProvider> metadataProviders) {
        super(dataSources, metadataProviders);
    }

    @Override
    protected AbstractHealthIndicator createIndicator(DataSource source) {
        DataSourceHealthIndicator indicator = (DataSourceHealthIndicator) super.createIndicator(source);
        if (!StringUtils.hasText(indicator.getQuery())) {
            indicator.setQuery(defaultQuery);
        }
        return indicator;
    }

}
