详解Mybatis中常用的约束文件
详解Mybatis中常用的约束文件
SqlMapConfig.xml的约束，也就是Mybatis主配置文件的约束
PUBLIC "lDyCCwsi-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
持久层接口映射文件的约束
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
日志文件的配置log4j.properties
```bash
# Set root category priority to INFO and its only appender to CONSOLE.
# log4j.rootCategory=INFO, CONSOLE debug info warn error fatal
log4j.rootCategory=debug, CONSOLE, LOGFILE
# Set the enterprise logger category to FATAL and its only appender to CONSOLE.
log4j.logger.org.apache.axis.enterprise=FATAL, CONSOLE
# CONSOLE is set to be a ConsoleAppender using a PatternLayout.
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n
# LOGFILE is set to be a File appender using a PatternLayout.
log4j.appender.LOGFILE=org.apache.log4j.FileAppender
#生成的日志文件的位置和命名
log4j.appender.LOGFILE.File=d:\axis.log
log4j.appender.LOGFILE.Append=true
log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout
log4j.appender.LOGFILE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n
PS:Mybatis xml约束文件的使用
一：准备.DTD约束文件

二：在eclipse中使用XML约束文件
将约束文件，插入到xml文件中，两种约束文件的插入位置是相同的
核心配置文件：
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-config.dtd">
sql映射文件：
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-mapper.dtd">
三：集成到eclipse开发工具中
Window-> Preferences->XML->XML Catalog->Add
然后
key：写入 xml文件中 PUBLIC中的值
Location：选择dtd文件的实际物理位置
