一、springBoot的作用
简化spring框架的搭建；springboot有自己特定的配置方式
二、springboot继承web(jsp)
1.导包
父模块
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.5.RELEASE</version>
</parent>
子模块添加spring-boot-starter-web依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- servlet 依赖. -->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
<!-- tomcat 的支持. -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>
2.配置application.properties对jsp的支持
# 页面默认前缀目录
spring.mvc.view.prefix=/WEB-INF/views/
# 响应页面默认后缀
spring.mvc.view.suffix=.jsp
3.controller层
//不适用@RestController是因为@RestController还包含@ResponBody
@Controller
public class JSPController {
@RequestMapping("/jsp")
public String jsp(Model model){
model.addAttribute("username", "只是测试一把");
return "hello";
}
}
4.编写jsp页面 hello.jsp
5.运行启动服务器
@SpringBootApplication
public class JSPapplication {
public static void main(String[] args){
SpringApplication.run(JSPapplication.class,args);
}
}
三、集成freemarker
1.导包
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>
2.配置文件application.properties
//设置文件路径，程序默认去resources文件夹下面找templates，所以下面的可以不用配置
spring.freemarker.tempalte-loader-path=classpath:/templates
//spring.freemarker.cache=false//缓存
//spring.freemarker.charset=UTF-8
//spring.freemarker.check-template-location=true
spring.freemarker.expose-session-attributes=true//暴露session的属性
spring.freemarker.allow-session-override=true//允许session属性覆盖
spring.freemarker.suffix=.ftl//设置后缀
3.controller层
@Controller
public class FreemarkerController {
@RequestMapping("/freemarker")
public String test(Model model){
model.addAttribute("username", "怡宝测试");
return "hello";
}
}
4.运行主配置类，启动服务器
@SpringBootApplication
public class FreemarkerApplication {
public static void main( String[] args ) {
springApplication.run(FreemarkerApplication.class,args);
}
}
四、springboot-test测试
1.导包
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- web支持: 1、web mvc; 2、restful; 3、jackjson支持; 4、aop ........ -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
</dependency>
2.controller层代码
@SpringBootApplication
public class SBTestApplication {
public static void main(String[] args){
SpringApplication.run(SBTestApplication.class);
}
}
3.测试代码--test
@RunWith(SpringRunner.class)
@SpringBootTest(classes = SBTestApplication.class)
//classes路径是Application的字节码文件
public class SBTest {
@Test
public void method(){
System.out.println("1111111");
}
}
五、springboot 持久化------集成JDBC
1.导包
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
2.配置数据库连接--application.properties(yml也可以)
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.url=jdbc:mysql:///crm
spring.datasource.driverClassName=com.mysql.jdbc.Driver
3.三层
1.Dao层
public interface JDBCDao {
List<Employee> findAll();
}
2.Dao.Impl层
@Repository
public class JDBCDaoImpl implements JDBCDao {
//注入数据库操作对象JdbcTemplate
@Autowired
private JdbcTemplate jdbcTemplate;
@Override
public List<Employee> findAll() {
String sql="select id,username,password from t_employee";
List<Employee> list = jdbcTemplate.query(sql, new BeanPropertyRowMapper<>(Employee.class));
return list;
}
}
3.service层
public interface JDBCService {
List<Employee> findAll();
}
4.service.impl层
@Service
public class JDBCServiceImpl implements JDBCService {
@Autowired
private JDBCDao jdbcDao;
@Override
public List<Employee> findAll() {
return jdbcDao.findAll();
}
}
5.controller层
@Controller
public class JDBCController {
@Autowired
private JDBCService jdbcService;
@RequestMapping("/findAll")
public void findAll(){
jdbcService.findAll();
}
}
6.Application类
@SpringBootApplication
//ComponentScan：配置注解扫描,扫描@service/@Repository等
@ComponentScan("cn.itsource")
public class JDBCApplication {
public static void main(String[] args){
SpringApplication.run(JDBCApplication.class);
}
}
7.测试类
@RunWith(SpringRunner.class)
@SpringBootTest(classes = JDBCApplication.class)
public class JdbcTest {
@Autowired
private JDBCService jdbcService;
@Test
public void method(){
//注入service层调用方法
List<Employee> employees = jdbcService.findAll();
for (Employee e:employees) {
System.out.println(e);
}
}
}
六、集成mybatis
1.导包
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
</dependency>
<!-- mysql 数据库驱动. -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
<!--
spring-boot mybatis依赖：请不要使用1.0.0版本，因为还不支持拦截器插件，
1.1.1 是博主写帖子时候的版本，大家使用最新版本即可
-->
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>1.1.1</version>
</dependency>
<!--
MyBatis提供了拦截器接口，我们可以实现自己的拦截器，
将其作为一个plugin装入到SqlSessionFactory中。
Github上有位开发者写了一个分页插件，我觉得使用起来还可以，挺方便的。
Github项目地址： https://github.com/pagehelper/Mybatis-PageHelper
-->
<dependency>
<groupId>com.github.pagehelper</groupId>
<artifactId>pagehelper</artifactId>
<version>4.1.0</version>
</dependency>
2.配置数据库
同上
3.配置三层 和 *mapper.xml文件
1.application类
@SpringBootApplication
//扫描mapper层的接口
@MapperScan(basePackages = "cn.itsource.mapper")
public class EmployeeApplication {
public static void main(String[] args){
SpringApplication.run(EmployeeApplication.class);
}
}
2.*mapper.xml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="cn.itsource.mapper.EmployeeMapper">
<select id="selectAll" resultType="cn.itsource.domain.Employee">
select id, username, password
from t_employee
</select>
</mapper>
3.application.properties配置文件
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.url=jdbc:mysql:///crm
spring.datasource.driverClassName=com.mysql.jdbc.Driver
//*mapper.xml扫描配置
mybatis.mapper-locations=classpath:cn/itsource/mapper/*.xml
4.测试类
@RunWith(SpringRunner.class)
@SpringBootTest(classes = EmployeeApplication.class)
public class MyTest {
@Autowired
private EmployeeService employeeService;
@Test
public void method(){
List<Employee> employees = employeeService.findAll();
for (Employee e:employees) {
System.out.println(e);
}
}
}
