SpringMVC 專案框架的搭建（javaweb專案）
阿新 • • 發佈：2018-12-11
1、首先建立一個java的mavenweb專案，即選擇war包。
2、由於剛建立的web工程缺少web.xml等相關的檔案，所以會出現一系列的錯誤，可以用兩種方法去改掉報錯。
第一種：手動新增其他java web專案下的下圖資料夾（需要包含web.xml檔案）放到專案的webapp的資料夾下面
第二種：在專案上右鍵，最後一個Properties選項，選擇Projects Facets，如下圖，在Dynamic Web Module選項上勾選Apply會出現下面的Futher Configuration available的連結，點進去
點進去之後會出現下面的彈出框，上面一個就是專案名不用改，下面一個改成src/main/webapp,然後確定，最後將Dynamic Web Module改成3.0在勾選上確定即會自動在webapp的目錄下面建立方法一中的兩個檔案和其中的web.xml檔案。
4、更改pom.xml檔案，新增需要的依賴，這裡我用的是一個總結版的pom直接放進去
pom.xml
4、新增spring.xml和springmvc的檔案<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.iflytek</groupId> <artifactId>myssh</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <properties> <spring.version>4.3.13.RELEASE</spring.version> </properties> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjrt</artifactId> <version>1.8.10</version> </dependency> <dependency> <groupId>aopalliance</groupId> <artifactId>aopalliance</artifactId> <version>1.0</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.8.10</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>4.3.11.Final</version> </dependency> <!-- web jar --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.0.1</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.1.2</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>javax.servlet.jsp-api</artifactId> <version>2.3.1</version> <scope>provided</scope> </dependency> <!-- jstl jar --> <!-- * compile，預設值，適用於所有階段，會隨著專案一起釋出。 * provided，類似compile，期望JDK、容器或使用者會提供這個依賴。如servlet.jar。 * runtime，只在執行時使用，如JDBC驅動，適用執行和測試階段。 * test，只在測試時使用，用於編譯和執行測試程式碼。不會隨專案釋出。 * system，類似provided，需要顯式提供包含依賴的jar，Maven不會在Repository中查詢它。 --> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <dependency> <groupId>taglibs</groupId> <artifactId>standard</artifactId> <version>1.1.2</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.38</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> <version>2.9.2</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.9.2</version> </dependency> </dependencies> </project>
這裡簡單配置一下識別註解，沒有很完善的功能
spring.xml
springmvc.xml<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd"> <context:component-scan base-package="com.iflytek"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> </beans>
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">
<context:component-scan base-package="com.iflytek">
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
</beans>
5、在web.xml中做相應的配置，將以上Spring.xml和springmvc.xml檔案載入到tomcat中，程式碼如下
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
id="WebApp_ID" version="3.0">

@Controller
public class HomeController {

public String goHome() {
return "/WEB-INF/jsp/home.jsp";
}
