Question

springmvc+mybatis怎么传值到xml

Answer 1

直接上代码 首先是从程序的入口开始说：
web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>

<!--
设置session过期的时间
-->
<session-config>
<session-timeout>20</session-timeout>
</session-config>

<!--
读取spring的配置文件
-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:config/spring.xml;classpath:config/spring-myBatis.xml</param-value>
</context-param>

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<listener>
<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
</listener>

<!--
设置字符编码，将所有的字符编码同意设置为utf-8
-->
<filter>
<filter-name>filterEncoding</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>
</filter>

<filter-mapping>
<filter-name>filterEncoding</filter-name>
<url-pattern>/</url-pattern>
</filter-mapping>

<!--
生成一次性验证码的servlet
-->
<servlet>
<servlet-name>verifyCode</servlet-name>
<servlet-class>com.longhang.tool.verifyCode.VerifyCodeServlet</servlet-class>
</servlet>

<!--
将所有*.do的请求交给springMVC的DispatcherServlet来处理
-->
<servlet>
<servlet-name>DispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:config/springMVC-config.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>

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

<servlet-mapping>
<servlet-name>DispatcherServlet</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
</web-app>

springMVC的配置文件

<?xml version="1.0" encoding="UTF-8"?>

关于mybatis的映射文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.longhang.dao.userDao.UserDao" >
<resultMap id = "baseResultMap" type = "com.longhang.entity.user.User">
<id column = "uid" property = "uid" jdbcType = "CHAR"/>
<result column = "loginname" property = "loginname" jdbcType = "VARCHAR"/>
<result column = "loginpass" property = "loginpass" jdbcType = "VARCHAR"/>
<result column = "email" property = "email" jdbcType = "VARCHAR"/>
<result column = "status" property = "status" jdbcType = "VARCHAR"/>
<result column = "activationCode" property = "activationCode" jdbcType = "CHAR"/>
</resultMap>

<sql id = "base_column_list">
uid,loginname,loginpass,email,status,activationCode
</sql>

<!--根据id查询
返回的类型为User
-->
<select id="findById" resultMap="baseResultMap" parameterType="java.lang.String" >
select
<include refid="base_column_list" />
from l_user
where uid = #{uid,jdbcType=CHAR}
</select>

<!--
根据activationCode查询
返回值是User
-->

<select id = "findByActivationCode" resultMap = "baseResultMap" parameterType = "java.lang.String">
select <include refid = "base_column_list"/>

where activationCode = #{activationCode}
