Spring Boot 框架搭建 （持续更新） 初学

最近学习Spring Boot，昨天下午把自己绕糊涂了，其实很简单，就像正常建工程一样，csdn太难贴图了，直说了。

首先建个maven，然后下面贴出各部分代码，tomcat我用的7.0自己下个配置上就行。

package com.base.application;import org.apache.ibatis.session.SqlSessionFactory;import org.apache.tomcat.jdbc.pool.DataSource;import org.mybatis.spring.SqlSessionFactoryBean;import org.mybatis.spring.annotation.MapperScan;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.EnableAutoConfiguration;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.boot.context.properties.ConfigurationProperties;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.ComponentScan;import org.springframework.core.io.support.PathMatchingResourcePatternResolver;import org.springframework.jdbc.datasource.DataSourceTransactionManager;import org.springframework.stereotype.Controller;import org.springframework.transaction.PlatformTransactionManager;import org.springframework.web.bind.annotation.RequestMapping;@EnableAutoConfiguration@Controller@SpringBootApplication@ComponentScan(basePackages={"com.base"})//指定spring管理的bean所在的包@MapperScan("com.base.mapping")//指定mybatis的mapper接口所在的包public class Application {   public static void main(String[] args) {      SpringApplication.run(Application.class, args);   }   //创建数据源   @Bean   @ConfigurationProperties(prefix = "spring.datasource")//指定数据源的前缀 ,在application.properties文件中指定   public DataSource dataSource() {      return new DataSource();   }   //创建SqlSessionFactory   @Bean   public SqlSessionFactory sqlSessionFactoryBean() throws Exception {      SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();      sqlSessionFactoryBean.setDataSource(dataSource());      PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();      sqlSessionFactoryBean.setMapperLocations(resolver.getResources("classpath:/mybatis/*.xml"));      return sqlSessionFactoryBean.getObject();   }   //创建事物管理器   @Bean   public PlatformTransactionManager transactionManager() {      return new DataSourceTransactionManager(dataSource());   }   @RequestMapping("/")   public String index(){      return "forward:/index/";   }}

IndexConreoller 

package com.base.controller;import org.springframework.ui.ModelMap;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;@RestController@RequestMapping("/index")public class IndexConreoller {    @RequestMapping("/")    public String index(ModelMap map){        return "Hello World!";    }}
