纯Java配置SpringMvc&Freemarker&JdbcTemplate

主要演示纯java配置springmvc+jdbcTemplate+Freemarker

与上一片（http://blog.csdn.net/niugang0920/article/details/79448171）列子相比主要变动了，pom.xml，SpringMvcConfig.java,及WEB-INF/views/下面页面的变化，重复代码就不在这里列出了1.pom.xml<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>
