spring項目搭建二(整合springmvc)

使用maven搭建了spring項目之後,整合springmvc,需要添加以下依賴:

<!-- 3.Spring web依賴 -->
    <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>

在此基礎上,還要添加json的處理,以及項目日誌依賴的添加

    <!--日誌-->
    <!-- SLF4J API -->
    <!-- SLF4J 是一個日誌抽象層，允許你使用任何一個日誌系統，並且可以隨時切換還不需要動到已經寫好的程序 -->
    <dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-api</artifactId>
      <version>${slf4j.version}</version>
    </dependency>
    <!-- Log4j 日誌系統（最常用） -->
    <dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-log4j12</artifactId>
      <version>${log4j.version}</version>
    </dependency>
    <!-- jackson json的處理依賴-->
    <!--jackson-databind依賴另外兩個jackson-core,jackson-annotations,故另外兩個可以不引用-->
    <dependency>
      <groupId>com.fasterxml.jackson.core</groupId>
      <artifactId>jackson-databind</artifactId>
      <version>${jackson.version}</version>
    </dependency>

pom.xml配置好之後,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"
             xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:p="http://www.springframework.org/schema/p"
             xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd ">
   <!--註解驅動-->
    <mvc:annotation-driven />
    <!-- ①：對web包中的所有類進行掃描，以完成Bean創建和自動依賴注入的功能 -->
    <context:component-scan base-package="com.happy" />
    <!-- 這個類用於Spring MVC視圖解析 -->
    <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分發器 -->
  <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>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
  <!--spring mvc 配置結束-->

此時完整的web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         metadata-complete="true" version="3.1">

  <!-- Spring的log4j監聽器 -->
  <listener>
    <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
  </listener>

  <!--配置spring-->

    <param-name>contextConfigLocation</param-name>
    <!--配置文件的路徑-->

  </context-param>
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <!--配置spring結束-->
  <!--spring mvc-->
  <!-- Spring view分發器 -->
  <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>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
  <!--spring mvc 配置結束-->

  <!-- 字符集 過濾器  -->
  <filter>
    <filter-name>CharacterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
    </init-param>
    <init-param>
      <param-name>forceEncoding</param-name>
      <param-value>true</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>

寫個controller測試下:

@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();
        }
    }

}

運行結果:

另外還有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
