Spring SpringMVC MyBatis配置笔记

工程大致结构：
project
|-src
|----pojo
|--------Temp.java

|----web
|--------TempController.java
|-resources
|----applicationContext.xml
|----springMVC.xml
|----mybatis-config.xml
|----db.properties
|----log4j.properties
|-webapp
|----WEB-INF
|--------web.xml
|-pom.xml

db.properties数据库配置文件

jdbcUrl=jdbc:mysql://localhost:3306/db_test?useUnicode=true&characterEncoding=UTF8

log4j.properties日志配置文件

log4j.rootLogger = ERROR , stdout
log4j.logger.your-package=DEBUG
log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target = System.out
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern = %d{yyyy-MM-dd HH:mm:ss} [%t] %-5p %c{1}:%L - %m%n

mybatis-config.xml

applicationContext.xml(这里没有分层）

springMVC.xml

    

    
        
        

            
                
                    UTF-8
                
            

            
        
    

    
    
    
    
    
        
        
    

web.xml

    
    
        encodingFilter
        org.springframework.web.filter.CharacterEncodingFilter
        
            encoding
            UTF-8
        
    

    
        encodingFilter
        /*
    
    
    
        contextConfigLocation
        classpath:applicationContext.xml
    
    
    
        org.springframework.web.context.ContextLoaderListener
    

    
        dispatcherServlet
        org.springframework.web.servlet.DispatcherServlet
        
            contextConfigLocation
            classpath:springMVC.xml
        
        1
        
        true
    

    
        dispatcherServlet
        /
    

再来，有java类TempDao、Temp：

public interface TempDao {

    Temp findTempById(int id);

    int insertTemp(Temp temp);

    int deleteTempById(int id);

    List findTemps();

    int updateTemp(Temp temp);
}

public class Temp {

    private int id;
    private String name;
    private String sex;
    private String text;
    
    //setter & getter
}

TempDao.xml

    
        SELECT * FROM tb_temp WHERE id = #{id}
    

    
        INSERT INTO tb_temp(username, sex, text) VALUES(#{username}, #{sex}, #{text})
    

    
        DELETE FROM tb_temp WHERE id = #{id}
    

    
        SELECT * FROM tb_temp
    

    
        UPDATE tb_temp SET username = #{username}, sex = #{sex} WHERE id = #{id}
