4.启动类
package com.zy;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.transaction.annotation.EnableTransactionManagement;
@SpringBootApplication
/*配置事务的注解，同时也需要在service层方法上添加注解*/
@EnableTransactionManagement
/*整合mybatis*/
@MapperScan("com.zy.mapper")
/*@可配可不配ComponentScan(basePackages = {"com.zy.service","com.zy.controller"})*/
public class SpringBoot01Application {
public static void main(String[] args) {
SpringApplication.run(SpringBoot01Application.class, args);
}
}
5.config包下类
package com.zy.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.Ordered;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
@Configuration
public class StaticResourceConfig extends WebMvcConfigurerAdapter {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
/*配置js,css等*/
registry.addResourceHandler("/js/**").addResourceLocations("WEB-INF/js/");
registry.addResourceHandler("/css/**").addResourceLocations("WEB-INF/css/");
registry.addResourceHandler("/fonts/**").addResourceLocations("WEB-INF/fonts/");
super.addResourceHandlers(registry);
}
@Override
public void addViewControllers(ViewControllerRegistry registry) {
/*配置默认访问页:需要在浏览器中输入ip+端口号*/
registry.addViewController("/").setViewName("forward:/index.jsp");
registry.setOrder(Ordered.HIGHEST_PRECEDENCE);
super.addViewControllers(registry);
}
}
6.util包下分页工具类
package com.zy.util;
import java.util.List;
public class StudentPageUtils {
private long totalPages;
private Integer pageSize;
private Integer currentPage;
private List rows;
@Override
public String toString() {
return "StudentPageUtils{" +
"totalPages=" + totalPages +
", pageSize=" + pageSize +
", currentPage=" + currentPage +
", rows=" + rows +
'}';
}
public long getTotalPages() {
return totalPages;
}
public void setTotalPages(long totalPages) {
this.totalPages = totalPages;
}
public Integer getPageSize() {
return pageSize;
}
public void setPageSize(Integer pageSize) {
this.pageSize = pageSize;
}
public Integer getCurrentPage() {
return currentPage;
}
public void setCurrentPage(Integer currentPage) {
this.currentPage = currentPage;
}
public List getRows() {
return rows;
}
public void setRows(List rows) {
this.rows = rows;
}
public StudentPageUtils() {
}
public StudentPageUtils(long totalPages, Integer pageSize, Integer currentPage, List rows) {
this.totalPages = totalPages;
this.pageSize = pageSize;
this.currentPage = currentPage;
this.rows = rows;
}
}
7.controller层
package com.zy.controller;
import com.github.pagehelper.PageHelper;
import com.github.pagehelper.PageInfo;
import com.zy.model.Student;
import com.zy.service.StudentServiceI;
import com.zy.util.StudentPageUtils;
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.RequestParam;
import java.util.List;
import java.util.Map;
@Controller
@RequestMapping("stu/")
public class StudentController {
@Autowired
private StudentServiceI studentServiceI;
// 查询学生信息，包括多条件查询
@RequestMapping("getStudentByCondition")
public String getStudentByCondition(Map map, Student student, @RequestParam(defaultValue = "1") Integer pageNo) {
PageHelper.startPage(pageNo, 2);
List list = studentServiceI.getStudentByCondition(student);
StudentPageUtils pageInfo = new StudentPageUtils();
pageInfo.setRows(list);
PageInfo pageInfoList = new PageInfo(list);
pageInfo.setTotalPages(pageInfoList.getPages());
pageInfo.setCurrentPage(pageNo);
pageInfo.setPageSize(pageInfoList.getPageSize());
map.put("pageInfo", pageInfo);
map.put("stu",student);
return "stu/stuList";
}
// 删除学生信息
@RequestMapping("deleteStu")
public String deleteStu(Integer id) {
studentServiceI.deleteStu(id);
return "redirect:/index.jsp";
}
// 增加学生信息
@RequestMapping("addStu")
public String addStu(Student student) {
studentServiceI.addStu(student);
return "redirect:/index.jsp";
}
// 更新学生信息
@RequestMapping("updateStu")
public String updateStu(Student student){
studentServiceI.updateStu(student);
return "redirect:/index.jsp";
}
// 根据id查询学生信息
@RequestMapping("getStudentById")
public String getStudentById(Integer id,Map map){
Student student = new Student();
student.setId(id);
List list = studentServiceI.getStudentByCondition(student);
StudentPageUtils pageInfo = new StudentPageUtils();
pageInfo.setRows(list);
map.put("pageInfo", pageInfo);
return "stu/updateStu";
}
}
8.service层实现类
package com.zy.service.impl;
import com.zy.mapper.StudentMapper;
import com.zy.model.Student;
import com.zy.service.StudentServiceI;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import java.util.List;
@Service(value="StudentServiceI")
/*配置事务注解*/
public class StudentServiceImpl implements StudentServiceI {
// 查询学生信息，多条件查询
@Autowired
private StudentMapper studentMapper;
@Override
public List getStudentByCondition(Student student) {
return studentMapper.getStudentByCondition(student);
}
// 删除学生
@Override
public void deleteStu(Integer id) {
studentMapper.deleteStu(id);
}
// 增加学生信息
@Override
public int addStu(Student student) {
int id = studentMapper.addStu(student);
return id;
}
// 修改学生信息
@Override
public void updateStu(Student student) {
studentMapper.updateStu(student);
}
}
9.mapper层接口
package com.zy.mapper;
import com.zy.model.Student;
import org.springframework.stereotype.Repository;
import java.util.List;
@Repository
public interface StudentMapper {
// 查询学生信息，多条件查询
List getStudentByCondition(Student student);
// 删除学生
void deleteStu(Integer id);
// 增加学生信息
int addStu(Student student);
// 修改学生信息
void updateStu(Student student);
}
10.model层实体类
package com.zy.model;
import java.io.Serializable;
public class Student implements Serializable {
private Integer id;
private String name;
private Integer age;
private String gender;
private String addr;
@Override
public String toString() {
return "Student{" +
"id=" + id +
", name='" + name + '\'' +
", age=" + age +
", gender='" + gender + '\'' +
", addr='" + addr + '\'' +
'}';
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
public String getGender() {
return gender;
}
public void setGender(String gender) {
this.gender = gender;
}
public String getAddr() {
return addr;
}
public void setAddr(String addr) {
this.addr = addr;
}
public Student() {
}
public Student(Integer id, String name, Integer age, String gender, String addr) {
this.id = id;
this.name = name;
this.age = age;
this.gender = gender;
this.addr = addr;
}
}
11.resources下的mybatis全局配置文件sqlMappingConfig.xml
12.mybatis其他文件
delete from stu
where id = #{id}
select last_insert_id()
insert into stu values(null,#{name},#{age},#{gender},#{addr})
update stu
set name=#{name},age=#{age},gender=#{gender},addr=#{addr}
where id=#{id}
13.webapp下的index.jsp

Title
1.15发布到linux服务器
1.15.1使用外部tomcat发布
org.springframework.boot
spring-boot-starter-web
org.springframework.boot
spring-boot-starter-tomcat
执行打包指令(注意,这里有web页面,所以是war包)
maven clean install -DskipTests=true
图片.png
然后,将该war包上传到tomcat的webapps目录下-->到tomcat的bin目录下: ./startup.sh启动即可
访问方式:ip:port/项目名/路径名
如:此处为:l92.168.0.199:8080/spring-boot01-0.0.1-SNAPSHOT/index.jsp
1.16采用nginx代理,转发请求
#将/hello请求转发给http://l92.168.0.199:8080/spring-boot01-0.0.1-SNAPSHOT处理(假设server的port是8081)
location /hello{
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://l92.168.0.199:8080/spring-boot01-0.0.1-SNAPSHOT;
}
如果用户在浏览器输入:
http://192.168.0.199:8081/hello/toJSP
那么实际的访问地址是:
http://l92.168.0.199:8081/spring-boot01-0.0.1-SNAPSHOT/toJSP
