通用解释 setCharacterEncoding只是设置字符的编码方式 setContentType除了可以设置字符的编码方式还能设置文档内容的类型 详细区别 request.setCharacterEncoding(“utf-8”); 是设置从request中取得的值或从数据库中取出的值, 比如
Enter Shift_JIS in the Character Encoding column.If a mapping is not set for the web application, setLocale uses a Application Server mapping.The first application in Chapter 5, JavaServer Pages Technology allows a user to choose an English string representation of a locale from all the locales...
我们在连接MySQL数据库的时候一般都会在url后面添加useUnicode=true&characterEncoding=UTF-8,但是问什么要添加呢? 添加的作用是:指定字符的编码、解码格式。 例如:mysql数据库用的是gbk编码,而项目数据库用的是utf-8编码。这时候如果添加了 useUnicode=true&characterEncoding=UTF-8 ,那么作用有如下两个方面: 1.存数...
In the Java SE API documentation, Unicode code point is used for character values in the range between U+0000 and U+10FFFF, and Unicode code unit is used for 16-bit char values that are code units of the UTF-16 encoding. For more information on Unicode terminology, refer to the Unicode...
Let’s see how we can configure this filter in a Spring Boot application. First, let’s create aCharacterEncodingFilter: CharacterEncodingFilter filter = new CharacterEncodingFilter(); filter.setEncoding("UTF-8"); filter.setForceEncoding(true); ...

第三步,更改连接字符串 原来的JDBC连接字符串是这样写的: jdbc:mysql://localhost:3306/db_xxxxx?useSSL=false& characterEncoding =utf8mb4 后来改成 jdbc:mysql://localhost:3306/db_xxxxx?useSSL=false& character_set_server =utf8mb4 问题解决
编译过程中报错 找不到HttpServletResponse的setCharacterEncoding()方法 查看源码时可以看到idea的反编译提示 是java1.2版本的 解决办法是 在pom中把所有springboot相关的依赖放到最前面 怀疑问题出在starter-web这个依赖上 刷新依赖可以看到方法不报错了 再次查看源码 看到版本变成了8...
改下字符集 修改mysql的默认字符集是通过修改它的配置文件来实现的。windows下的mysql配置文件是my.ini,一般在c:\windows\my.ini或者c:\winnt\my.ini可以直接在这个文件里面加上 default-character-set=gbk #或gb2312,big5,utf8 然后重新启动mysql service mysql restart 设置...
