一、注入依赖

		 junitjunit3.8.1testjavax.servletjavax.servlet-api4.0.1providedorg.springframeworkspring-webmvc4.3.23.RELEASEorg.springframeworkspring-jdbc4.3.23.RELEASEmysqlmysql-connector-java8.0.26com.mchangec3p00.9.5.5javax.servletjstl1.2com.alibabafastjson1.2.47log4jlog4j1.2.17org.mybatismybatis3.5.7org.mybatismybatis-spring2.0.6

二、配置web.xml

spring-springMVC20221121login.jspcharacterEncodingFilterorg.springframework.web.filter.CharacterEncodingFilterencodingUTF-8characterEncodingFilter/*contextConfigLocationclasspath:applicationContext.xmlorg.springframework.web.context.ContextLoaderListenerspringmvcorg.springframework.web.servlet.DispatcherServletcontextConfigLocationclasspath:springmvc-common.xmlspringmvc/

三、springmvc-common.xml配置

四、mybatis-config.xml配置

五、log4j.properties日志文件配置

#LOG_DIR:/usr/local/.../logs\
LOG_DIR = E:\\logs
#Level:ERROR,WARN,INFO,DEBUG
log4j.rootLogger = INFO,Console,File
log4j.appender.Console = org.apache.log4j.ConsoleAppender
log4j.appender.Console.Threshold = DEBUG
log4j.appender.Console.ImmediateFlush = true
log4j.appender.Console.Target = System.out
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern = [%-5p] %d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n
log4j.appender.File = org.apache.log4j.DailyRollingFileAppender
log4j.appender.File.Threshold = INFO
log4j.appender.File.ImmediateFlush = true
log4j.appender.File.Append = true
log4j.appender.File.DatePattern = '_'yyyy-MM-dd'.log'
log4j.appender.File.encoding=UTF-8
log4j.appender.File.File = ${LOG_DIR}/info
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern = [%-5p][%d{ISO8601}]%m%n

六、jdbc.properties连接信息

根据个人连接数据库信息更改

a=jdbc:mysql://localhost:3306/test?characterEncoding=UTF-8
b=root
c=123
d=com.mysql.cj.jdbc.Driver

七、applicationContext.xml配置

classpath:jdbc.properties				

八、UserDao.xml案例

insert into tb_user (uname,upwd,email,phone,addr,birth)values(#{uname},#{upwd},#{email},#{phone},#{addr},#{birth})

九、UserService接口

public interface UserService {void insertUser(User user);
}

十、UserServiceImpl实现

@Service
public class UserServiceImpl implements UserService {@Autowiredprivate UserDao userDao;@Overridepublic void insertUser(User user) {userDao.addUser(user);}}

十一、MyConverter

public class MyConverter implements Converter{@Overridepublic Date convert(String source) {SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd");try {Date d=sdf.parse(source);return d;} catch (ParseException e) {e.printStackTrace();return null;}}}

十二、UserController

@Controller
@RequestMapping("/user")
public class UserController {@Autowiredprivate UserService userService;@RequestMapping("/reg")public String reg(User user) {userService.insertUser(user);return "login";}
}
