SpringMVC配置式开发

一.PropertiesMethodResolver 属性配置开发

实体类创建：

public class Multi extends MultiActionController {
/*
    public String doFirst(){
        return "First";
    }*/
    public String doFirst(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {
        return "First";
    }

    public String doSecond(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {
        return "Second";
    }
}

xml配置：

    <bean id="second" class="day01.Multi">
        <property name="methodNameResolver" ref="propertiesMethod"></property>
    </bean>
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>
    <!--属性配置式开发-->
    <bean id="propertiesMethod" class="org.springframework.web.servlet.mvc.multiaction.PropertiesMethodNameResolver">
        <property name="mappings">
            <props>
                <prop key="/myfirst">doFirst</prop>
                <prop key="/mysecond">doSecond</prop>
            </props>
        </property>
    </bean>
  <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="urlMap">
            <map>
                <entry key="/*" value="second"></entry>
            </map>
        </property>
    </bean>

web.xml配置：

  <servlet>
    <servlet-name>springmvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springMvcday03properties.xml</param-value>
    </init-param>

    <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

二.ParameterMethodResolver 参数方法名解析器

实体类创建：

public class BeanNameResolvetTest extends MultiActionController {
/*
    public String doFirst(){
        return "First";
    }*/
    public String doFirst(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {

        return "InnerReslover";
    }

    public String doSecond(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {

        return "OutResolver";
    }
}

xml配置：

    <bean id="second" class="day05.BeanNameResolvetTest">
        <property name="methodNameResolver" ref="paramMethod"></property>
    </bean>

    <!--视图解析器-->
    <bean id="beanNameMethod" class="org.springframework.web.servlet.view.BeanNameViewResolver"></bean>

    <!--外部资源-->
<bean id="OutResolver" class="org.springframework.web.servlet.view.RedirectView">
    <property name="url" value="https://www.jd.com"></property>
</bean>
    <!--内部资源-->
 <bean id="InnerReslover" class="org.springframework.web.servlet.view.JstlView">
        <property name="url" value="/Second.jsp"></property>
    </bean>

    <!--参数配置式开发-->
    <bean id="paramMethod" class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver">
       <property name="paramName" value="actionName"></property>
     </bean>

  <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="urlMap">
            <map>
                <entry key="/doFirst" value="second"></entry>
            </map>
        </property>
    </bean>
