@790477691 It may be that the version of snakeyaml that springframework depends on is too low, please try to specify the version of snakeyaml in the pom

<dependency>
     <groupId>org.yaml</groupId>
     <artifactId>snakeyaml</artifactId>
     <version>1.33</version>
</dependency>

I think the key is this,

No single argument constructor found for interface org.apache.shardingsphere.infra.yaml.config.pojo.rule.YamlRuleConfiguration

But why is this a problem

@RaigorJiang 

org.apache.shardingsphere:shardingsphere-infra-common:5.3.1
package org.apache.shardingsphere.infra.yaml.config.pojo.rule;

import org.apache.shardingsphere.infra.config.rule.RuleConfiguration;
import org.apache.shardingsphere.infra.util.yaml.YamlConfiguration;

/**
 * YAML rule configuration.
 */
public interface YamlRuleConfiguration extends YamlConfiguration {

    /**
     * Get rule configuration type.
     * 
     * @return rule configuration type
     */
    Class<? extends RuleConfiguration> getRuleConfigurationType();
}

This interface really doesn't have a single argument constructor

Get the interface YamlRuleConfiguration constructor to return an empty array and error 微信截图_20230130095157

@790477691 Can you provide a demo project?

790477691 commented 1 year ago

@zhaojinchao95 Here's a test project https://github.com/790477691/shardingJdbcTest.git

790477691 commented 1 year ago

@zhaojinchao95 shardingsphere jdbc + spring; Are there any examples that can be used？

Use example-generator to generate various example projects. https://github.com/apache/shardingsphere/tree/master/examples/shardingsphere-example-generator

RaigorJiang commented 1 year ago

@790477691 I think it is duplicated with #23143, can you have a check?
