1.在@Select中
@Select("<script>"
+ "SELECT IDFA FROM t_xxx WHERE IDFA IN "
+ "<foreach item=‘item‘ index=‘index‘ collection=‘strList‘ open=‘(‘ separator=‘,‘ close=‘)‘>"
+ "#{item}"
+ "</foreach>"
+ "</script>")
@Results(value = { @Result(column = "user_name", property = "username") })
public List<String> getXxxList(@Param("strList") List<String> strList);
说明:上述方式其实是一种注解完全代替xml的方法。
其中的foreach的collection直接写成@param中的值即可。

2.将入参进行封装,成(**,**,**,**,)
@Select("select access_pat_id from emr3.gp_doc_patients where access_pat_id in (#{apis}) and admission_time = (select max(admission_time) from emr3.gp_doc_patients where access_pat_id in (#{apis}))")
String getMaxTime(@Param("apis")String apis);
public static String indexForm(List<String> s){
String content="";
int i=0;
for (String ss:s){
i++;
if (i==s.size()){
content+=ss;
}else {
content+=ss+",";
}
}
return content;
}
该方法返回值就是入参apis
