Sprng Form Handling－Codeless的部落格

Spging mvc 可以針對簡單的form去處理(結合JSTL)。

web.xml

<display-name>Spring MVC Form Handling</display-name>
<session-config>
    <session-timeout>
        30
    </session-timeout>
</session-config>
<servlet>
    <servlet-name>HelloWeb</servlet-name>
    <servlet-class>
                   org.springframework.web.servlet.DispatcherServlet
    </servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring-config.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>HelloWeb</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

spring-config.xml

<context:component-scan base-package="com.example" />
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
  <property name="prefix" value="/WEB-INF/jsp/" />
  <property name="suffix" value=".jsp" />
</bean>

Customer.java
