SpringMVC之整合框架和Ajax

整合框架：

<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:applicationContext.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>

mybatis自动托管；

<bean id="configurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="sqlSessionFactoryBeanName" value="sessionFactory"/>
        <property name="basePackage" value="com.saxon.Dao.User"/>
    </bean>

Ajax

一、例子

function a() {
            $.ajax({
                url: "http://localhost:8080/SpringMVC_02_war_exploded/saxon",
                data: {"userName": $("#userName").val()},
                type:"GET",
                success: function (data) {
                    console.log(data)
                }
            })
        }

使用get或者post 会出现问题，使用ajax，加上type就可以正常使用

function a() {
            $.get({
                url: "http://localhost:8080/SpringMVC_02_war_exploded/saxon",
                data: {"userName": $("#userName").val()},
                success: function (data) {
                    if (data=="true"){
                        $("#username-span").text("ok");
                        $("#username-span").css("color","green");
                    }
                }
            })
        }
