## Bug Report **For English only**, other languages will not accept. Before report a bug, make sure you have: - Searched open and closed [GitHub issues](https://github.com/apache/shardingsphere/issues). - Read documentation: [ShardingSphere Doc](https://shardingsphere.apache.org/document/current/en/overview). Please pay attention on issues you submitted, because we maybe need more details. If no response anymore and we cannot reproduce it on current information, we will **close it**. Please answer these questions before submitting your issue. Thanks! ### Which version of ShardingSphere did you use? ``` <groupId>org.apache.shardingsphere</groupId> <artifactId>shardingsphere-jdbc-core-spring-boot-starter</artifactId> <version>5.1.1</version> ``` ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy? * ShardingSphere-JDBC ### Expected behavior * init druid datasource success * project start up success ### Actual behavior ### Reason analyze (If you can) ``` private Optional<Method> findSetterMethod(final String fieldName) { String setterMethodName = SETTER_PREFIX + CaseFormat.LOWER_CAMEL.to(CaseFormat.UPPER_CAMEL, fieldName); return Arrays.stream(dataSourceMethods).filter(each -> each.getName().equals(setterMethodName) && 1 == each.getParameterTypes().length).findFirst(); } ``` ``` public void setConnectProperties(Properties properties) public void setConnectionProperties(String connectionProperties) ``` **in class DataSourceReflection method findSetterMethod(final String fieldName),param -> "connectProperties", after filter return two Method, but findFirst() choose setConnectProperties(Properties properties). so errors ** **in version 4.1.1 no errors** ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc. ``` org.springframework.beans.factory.BeanCreationException: Error creating bean with name
