springboot+mybatis+freemark+oauth開發環境搭建

1、建立springboot工程

1.環境介紹：

a：jdk版本：1.7html

b：Springboot版本：1.5.6（使用1.5.9的版本整合mybatis會報錯：java.lang.NoClassDefFoundError: org/springframework/dao/support/DaoSupport）java

c：工程類型：maven工程mysql

2.建立maven工程：

2、springboot整合mybatis：

1.添加依賴：

<dependency>
　　<groupId>org.springframework.boot</groupId>
　　<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!--添加Mybatis依賴 -->
<dependency> 
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>1.3.1</version>
</dependency>
<!--添加MySQL驅動依賴 -->
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
</dependency>

2.配置application.properties：

#端口設置（默認8080）
server.port=9090
#數據庫相關配置
spring.datasource.url=jdbc:mysql://localhost:3306/test spring.datasource.username=root spring.datasource.password= spring.datasource.driver-class-name=com.mysql.jdbc.Driver

#mybatis相關配置
mybatis.type-aliases-package=com.example.bean
mybatis.mapper-locations=classpath:mapper/*.xml

3.編寫控制層、業務層代碼：

a：UserController.javaweb

package com.example.controller; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.servlet.ModelAndView; import com.example.service.UserService; @Controller @RequestMapping(value = "/user") public class UserController { @Autowired private UserService userService; @RequestMapping(value = "/selectAll",method=RequestMethod.GET) public ModelAndView selectAll(){ ModelAndView mv = new ModelAndView(); mv = userService.selectAll(); return mv; } }

b：UserService.java(service接口)spring

package com.example.service; import org.springframework.web.servlet.ModelAndView; public interface UserService { public ModelAndView selectAll(); }

c：UserServiceImpl.java(service實現)sql

package com.example.service.impl; import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import org.springframework.web.servlet.ModelAndView; import com.example.bean.User; import com.example.dao.UserDao; import com.example.service.UserService; @Service(value = "userService") public class UserServiceImpl implements UserService{ @Autowired private UserDao userDao; @Override public ModelAndView selectAll() { ModelAndView mv = new ModelAndView(); List<User> list = userDao.selectAll(); for (User user : list) { System.out.println(user); } mv.addObject("userList", list); mv.setViewName("demo"); return mv; } }

d：UserDao.java(dao層接口)數據庫

package com.example.dao; import java.util.List; import com.example.bean.User; public interface UserDao { public List<User> selectAll(); }

e：UserMapper.xml(mybatis的mapper.xml文件)apache

<?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.example.dao.UserDao">

    <resultMap id="BaseResultMap" type="com.example.bean.User" >
        <id column="pkid" property="pkid" jdbcType="INTEGER" />
        <result column="userName" property="userName" jdbcType="VARCHAR" />
        <result column="passWord" property="passWord" jdbcType="VARCHAR" />
        <result column="userInfo" property="userInfo" jdbcType="VARCHAR" />
      </resultMap>

    <select id="selectAll" resultMap="BaseResultMap"> select * from user where 1=1 </select>
</mapper>

f：數據庫表及數據：瀏覽器

CREATE TABLE `user` ( `pkid` int(10) NOT NULL DEFAULT '0', `userName` varchar(20) DEFAULT NULL, `passWord` varchar(20) DEFAULT NULL, `userInfo` varchar(100) DEFAULT NULL, PRIMARY KEY (`pkid`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

g：SpringbootApplication.java(springboot啓動類配置)springboot

package com.example; import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication @MapperScan("com.example.dao") public class SpringbootMybatisDemoApplication { public static void main(String[] args) { SpringApplication.run(SpringbootMybatisDemoApplication.class, args); } }

3、springboot整合freemark：

1.添加依賴：

<!-- 添加freemark依賴 -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>

2.添加application.propertis配置:

#freemark配置 spring.freemarker.template-loader-path=classpath:/templates/
spring.freemarker.suffix=.ftl

注：springboot整合freemark後，默認模板的後綴就是.ftl，所以，上面配置文件中的spring.freemarker.suffix=.ftl能夠省略。

3.建立freemark模板文件：

在resources文件夾下建立templates文件夾用於存放.ftl模板文件

demo.ftl文件內容以下：

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
    <h1>用戶信息表：</h1><hr/>
    <table>
        <tr>
            <td>用戶ID</td>
            <td>用戶名</td>
            <td>密碼</td>
            <td>用戶信息</td>
        </tr>
        <#list userList as item>
            <tr>
                <td>${item.pkid}</td>
                <td>${item.userName}</td>
                <td>${item.passWord}</td>
                <td>${item.userInfo}</td>
            </tr>
        </#list>
    </table>
</body>
</html>

4.工程結構圖：

這裏再貼一個完整的pom.xml文件吧：

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

    <groupId>com.example</groupId>
    <artifactId>Springboot_mybatis_demo</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>jar</packaging>

    <name>Springboot_mybatis_demo</name>
    <description>Demo project for Spring Boot</description>

        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <properties>

        <dependency>

            <artifactId>spring-boot-starter</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        
        <!--添加Web依賴 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        
        <!--添加Mybatis依賴 -->
        <dependency> 
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>1.3.0</version>
        </dependency>
        <!--添加MySQL驅動依賴 -->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
        </dependency>
        <!-- 添加freemark依賴 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-freemarker</artifactId>
        </dependency>
        
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>


</project>

至此，Springboot整合mybatis，Springboot整合freemark的全部配置就完成了，啓動springboot項目，瀏覽器輸入127.0.0.1:9090/user/selectAll測試效果以下：

5.效果圖：

4、springboot整合oauth：

還在整合，待續。。。
