Invalid byte 3 of 3-byte UTF-8 sequence

遇到这类错误,一般都是编码问题导致,文件编码、保存时的编码都要保持一致,如果尝试了好多次并且确定所有编码均为UTF-8还报下面的错误,

建议将xml文件顶部的encoding="UTF-8"  改为  encoding="GBK"

详细错误:

严重: Servlet.service() for servlet ReportServlet threw exception

大概就这样。

这样的问题一般都是编码不一致所致。

 

 

到这里如果还是有问题,那么再推荐一种做法,我是用的这种方式解决的,就是改变读取方式,在我这里造成前面所有错误的根源是我使用了Reader读取配置文件,那么这里我将Reader换了,原来报错的代码片段:


 1 package com.hedh.Util;
 2 
 3 import java.io.IOException;
 4 import java.io.Reader;
 5 
 6 import org.apache.ibatis.io.Resources;
 7 import org.apache.ibatis.session.SqlSessionFactory;
 8 import org.apache.ibatis.session.SqlSessionFactoryBuilder;
 9 
10 public class MybatisUtils {
11     private final static SqlSessionFactory SQL_SESSION_FACTORY;
12     static{
13         String resource="mybatis-config.xml";
14         Reader reader=null;
15         try{
16             reader = Resources.getResourceAsReader(resource);
17         }catch(IOException e){
18             e.printStackTrace();
19         }
20         SQL_SESSION_FACTORY=new SqlSessionFactoryBuilder().build(reader);
21     }
22     public static SqlSessionFactory getSqlSessionFactory(){
23         return SQL_SESSION_FACTORY;
24     }
25 }

 

 

将代码中的Reader更换了(注意两段代码的14行、16行、20行):

 1 package com.hedh.Util;
 2 
 3 import java.io.IOException;
 4 import java.io.Reader;
 5 
 6 import org.apache.ibatis.io.Resources;
 7 import org.apache.ibatis.session.SqlSessionFactory;
 8 import org.apache.ibatis.session.SqlSessionFactoryBuilder;
 9 
10 public class MybatisUtils {
11     private final static SqlSessionFactory SQL_SESSION_FACTORY;
12     static{
13         String resource="mybatis-config.xml";
14         InputStream in = null;
15         try{
16             in = Resources.class.getResourceAsStream(resource);
17         }catch(IOException e){
18             e.printStackTrace();
19         }
20         SQL_SESSION_FACTORY=new SqlSessionFactoryBuilder().build(in);
21     }
22     public static SqlSessionFactory getSqlSessionFactory(){
23         return SQL_SESSION_FACTORY;
24     }
25 }

这样子我的错误问题是解决了。问题根源我也想的还不是太清楚,好像是读取方式的问题。
