springboot动态调用实现类

定义规则的多种类型



public enum RuleType {
    MYRULEBYID1，
    MYRULEBYID2
}

接口


import java.util.List;
import java.util.Map;
 
public interface DataRuleParse {
    
      RuleType getRuleType();
 
    
   List<String> getsql( Map<String,Object> paramMap);
}

实现类，规则类型1


package gds.application.masterdata.DataRuleParse; 
import gds.application.common.constants.ConnectorConstants;
import gds.application.common.constants.XmlConfigurationContants;
import gds.application.common.util.ApplicationContextUtil;
import gds.application.masterdata.constants.ConnectDataProcessesConstants;
import gds.application.masterdata.service.impl.BatchExecutionSqlServiceImpl;
import org.springframework.stereotype.Component;  
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
 
@Component
public class MYRULEBYID1 implements DataRuleParse{   
    @Override
    public RuleType getRuleType() {
        return RuleType.MYRULEBYID1;
    }
 
    @Override
    public List<String> getSQl( Map<String,Object> paramMap) {
       //规则1实现方法
        return null;
    }

实现类，规则类型2


package gds.application.masterdata.DataRuleParse; 
import gds.application.common.constants.ConnectorConstants;
import gds.application.common.constants.XmlConfigurationContants;
import gds.application.common.util.ApplicationContextUtil;
import gds.application.masterdata.constants.ConnectDataProcessesConstants;
import gds.application.masterdata.service.impl.BatchExecutionSqlServiceImpl;
import org.springframework.stereotype.Component;  
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
 
@Component
public class MYRULEBYID2 implements DataRuleParse{   
    @Override
    public RuleType getRuleType() {
        return RuleType.MYRULEBYID2;
    }
 
    @Override
    public List<String> getSQl( Map<String,Object> paramMap) {
       //规则2实现方法
        return null;
    }

工厂类，调用方法获取具体实现类


import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component; 
import java.util.HashMap;
import java.util.Map;
 

@Component
public class DataRuleParseFactory implements ApplicationContextAware {
    private static Map<String, DataRuleParse> dataRuleBeanMap;
    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException{
        Map<String, DataRuleParse> map = applicationContext.getBeansOfType(DataRuleParse.class);
        dataRuleBeanMap = new HashMap<String, DataRuleParse>();
        map.forEach((key, value) -> dataRuleBeanMap.put(value.getRuleType().toString(), value));
    }
 
    public static <T extends DataRuleParse> T getTrafficMode(String ruleType) {
        return (T)dataRuleBeanMap.get(ruleType);
    }
}

根据参数获取对应的方法,ruleName为MYRULEBYID1或者MYRULEBYID2


  DataRuleParse dataRuleParse= DataRuleParseFactory.getTrafficMode(ruleName);
  List<String> sqlList=dataRuleParse.getSQl(paramMap);

springboot手动获取实现类


import org.springframework.WEB.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;
WebApplicationContext cxt = WebApplicationContextUtils.getWebApplicationContext(sc);
weixinService = (IWeixinService) cxt.getBean("IWeixinService");
qqService = (IQQService) cxt.getBean("IQQService");

以上为个人经验，希望能给大家一个参考，也希望大家多多支持编程网。
