直接向数据库里插入数据乱码

1,尝试引入Iso2Utf

package com.dafu.util;

public class Iso2Utf {
    public static String encode(String searchText){
        if (null != searchText&&!searchText.equals("")) {
            try {
                searchText = new String(searchText.getBytes("ISO-8859-1"), "UTF-8");
            } catch (Exception e) {
                e.printStackTrace();
            }
        }else{
            searchText="";
        }
        return searchText;
    }
}

String str=Iso2Utf.encode(str);

2,在jdbc，url数据库后边加修改编码格式

?useUnicode=true&characterEncoding=UTF-8

jdbc.url=jdbc:mysql://localhost:3306/HelloWorld?useUnicode=true&characterEncoding=UTF-8
