（2）修改配置文件application.properties
關鍵點2:

tm.manager.url=http://127.0.0.1:7000/tx/manager/

（3） 添加文件TxManagerTxUrlServiceImpl（關鍵3）

package com.jh.service.impl;

import com.codingapi.tx.config.service.TxManagerTxUrlService;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Service;

/**
 *  //關鍵點3:
 */
@Service
public class TxManagerTxUrlServiceImpl implements TxManagerTxUrlService{
    @Value("${tm.manager.url}")
    private String url;
    @Override
    public String getTxUrl() {
        System.out.println("load tm.manager.url ");
        return url;
    }
}
 

（4）服務層函數上加上@Transactional和@TxTransaction/（關鍵4）

  @TxTransaction//關鍵點，非常關鍵，否則沒效果
@Transactional
    public int saveTheme(String tName, String tDescription, Integer blockId) {
            int rs1 = themeDao.saveTheme(tName, tDescription, blockId);// 保存1
        return rs1;

    }
