使用maven搭建了spring项目之后,整合springmvc,需要添加以下依赖:
<!-- 3.Spring web依赖 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>${spring.version}</version>
</dependency>
<!-- spring mvc 框架 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>${spring.version}</version>
</dependency>
<!--支持servlet-->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
<scope>provided</scope>
</dependency>在此基础上,还要添加json的处理,以及项目日志依赖的添加
<!--日志-->
<!-- SLF4J API -->
<!-- SLF4J 是一个日志抽象层，允许你使用任何一个日志系统，并且可以随时切换还不需要动到已经写好的程序 -->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>${slf4j.version}</version>
</dependency>
<!-- Log4j 日志系统（最常用） -->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>${log4j.version}</version>
</dependency>
<!-- jackson json的处理依赖-->
<!--jackson-databind依赖另外两个jackson-core,jackson-annotations,故另外两个可以不引用-->
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>${jackson.version}</version>
</dependency>此时的pom.xml为:

</project>pom.xml配置好之后,配置下springmvc的配置文件
<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns:beans="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd ">
<!--注解驱动-->
<mvc:annotation-driven />
<!-- ①：对web包中的所有类进行扫描，以完成Bean创建和自动依赖注入的功能 -->
<context:component-scan base-package="com.happy" />
<!-- 这个类用于Spring MVC视图解析 -->
<beans:bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<beans:property name="prefix" value="/WEB-INF/views/" />
<beans:property name="suffix" value=".jsp" />
</beans:bean>
</beans:beans>web.xml中配置mvc的配置:
<!--spring mvc-->
<!-- Spring view分发器 -->
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:spring-mvc.xml</param-value>

<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!--spring mvc 配置结束-->此时完整的web.xml:
<?xml version="1.0" encoding="UTF-8"?>

</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>写个controller测试下:
@Controller
@RequestMapping("/user")
public class UserController {
@Autowired
private UserService userService;
@RequestMapping("/find")
public void findUser(HttpServletRequest request, HttpServletResponse response, @RequestParam("userName") String userName){
User user = userService.getUserByName(userName);
System.out.println("=====================find=============================");
try {
response.getWriter().write("user:"+user.toString());
} catch (IOException e) {
e.printStackTrace();
}
}
}运行结果:
另外还有log4j.properties:
# Priorities are: DEBUG, INFO, WARN, ERROR, or FATAL.
log4j.rootCategory=INFO, CONSOLE, FILE
logs.dir=${catalina.base}/logs/springdemo/
logs.filename=logs
fileBufferSize=20480
#log to File
log4j.appender.FILE=org.apache.log4j.DailyRollingFileAppender
log4j.appender.FILE.File=${webapp.root}/logs/test.log
log4j.appender.FILE.encoding=UTF-8
log4j.appender.FILE.Append=true
log4j.appender.FILE.LocationInfo=true
log4j.appender.FILE.DatePattern='.'yyyy-MM-dd'.log'
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
log4j.appender.FILE.layout.ConversionPattern=[%-5p] %d(%r) --> %l: %m %x %n
log4j.appender.FILE.bufferSize=${fileBufferSize}
# CONSOLE is set to be a ConsoleAppender using a PatternLayout.
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.Threshold=DEBUG
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=- %m%n
此时项目结构:
