字符串 批量删除 及转map

传入的字符串：organizationId  需要转换成 organizationId.split(',') 数组才能 遍历

<if test="organizationId !=null ">
  AND users.organization_id IN
  <foreach collection="organizationId.split(',')" item="organization" open="(" separator="," close=")">
    #{organization}
  </foreach>



字符串转map ：

Map<String, String> map =new HashMap();
map.put("a","aa");
map.put("c","aa");
String ss="{1:false,2:false}";
String[] split = StringUtils.split(ss, "|");
System.out.println(map);
for (Map.Entry<String, String> MapString : map.entrySet()) {
    String key=MapString.getKey();//次方法获取键值对的名称
    String value=MapString.getValue();//次方法获取键值对的值
    System.out.println(key+":"+value);
}
for (int i = 0; i <split.length ; i++) {
    System.out.println(split[i]);

}
