涉及到字符串中有多个数据需要替换使用StringBuffer

String docExtrefobjfield11=StringHelper.null2String(docMap.get("extrefobjfield11"));//团队成员
StringBuilder updatePeopleTeam = new StringBuilder();
if (StringHelper.isNotEmpty(docExtrefobjfield11)){
    String []hrids=docExtrefobjfield11.split(",");
    for (int k=0;k<hrids.length;k++){
        if (hrids[k].equals(personbeforechange)){
            continue;
        }
        updatePeopleTeam.append(hrids[k]);
        updatePeopleTeam.append(",");
    }
    if (StringHelper.isNotEmpty(personafterchange)){
        updatePeopleTeam.append(personafterchange);
    }

}else {
    updatePeopleTeam.append(personafterchange);
}
