個人分類： Spring

專案用Inteli做的，

第一步：新建專案

第二步：配置pom.xml

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

2. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

3. xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

4. <modelVersion>4.0.0</modelVersion>

5.  

6. <groupId>com.example</groupId>

7. <artifactId>demo</artifactId>

8. <version>0.0.1-SNAPSHOT</version>

9. <packaging>jar</packaging>

10.  

11. <name>demo</name>

12. <description>Demo project for Spring Boot</description>

13.  

14. <parent>

15. <groupId>org.springframework.boot</groupId>

16. <artifactId>spring-boot-starter-parent</artifactId>

17. <version>1.5.7.RELEASE</version>

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

19. </parent>

20.  

21. <properties>

22. <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

23. <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

24. <java.version>1.8</java.version>

25. </properties>

26.  

27. <dependencies>

28. <dependency>

29. <groupId>org.springframework.boot</groupId>

30. <artifactId>spring-boot-starter-aop</artifactId>

31. </dependency>

32. <dependency>

33. <groupId>org.springframework.boot</groupId>

34. <artifactId>spring-boot-starter-jdbc</artifactId>

35. </dependency>

36. <dependency>

37. <groupId>org.mybatis.spring.boot</groupId>

38. <artifactId>mybatis-spring-boot-starter</artifactId>

39. <version>1.3.1</version>

40. </dependency>

41. <dependency>

42. <groupId>org.springframework.boot</groupId>

43. <artifactId>spring-boot-starter-web</artifactId>

44. </dependency>

45.  

46. <dependency>

47. <groupId>mysql</groupId>

51. <dependency>

52. <groupId>org.springframework.boot</groupId>

53. <artifactId>spring-boot-starter-test</artifactId>

54. <scope>test</scope>

55. </dependency>

56. </dependencies>

57.  

58. <build>

59. <plugins>

60. <plugin>

61. <groupId>org.springframework.boot</groupId>

62. <artifactId>spring-boot-maven-plugin</artifactId>

63. </plugin>

64. </plugins>

65. </build>

66.  
67.  

68. </project>

69.  

第三步：建立資料庫

第四步：建立目錄

第五步：建立Student.java實體類

Student.java

1. package com.example.models;

2.  

3. public class Student {

4. private int id;

5. private String name;

6. private String sex;

7. private int age;

8.  

9. public int getId() {

10. return id;

11. }

12.  

13. public void setId(int id) {

14. this.id = id;

15. }

16.  

17. public String getName() {

18. return name;

19. }

20.  

21. public void setName(String name) {

22. this.name = name;

23. }

24.  

25. public String getSex() {

26. return sex;

27. }

28.  

29. public void setSex(String sex) {

30. this.sex = sex;

31. }

32.  

33. public int getAge() {

34. return age;

35. }

36.  

37. public void setAge(int age) {

38. this.age = age;

39. }

40.  

41. @Override

42. public String toString() {

43. return "Student{" +

44. "id=" + id +

45. ", name='" + name + '\'' +

46. ", sex='" + sex + '\'' +

47. ", age=" + age +

48. '}';

49. }

50. }

第六步：建立Mapper介面

StudentMapper.java

1. package com.example.Dao;

2.  

3. import com.example.models.Student;

4. import org.apache.ibatis.annotations.Select;

5. import org.springframework.stereotype.Repository;

6.  

7. @Repository

8. public interface StudentMapper {

9. @Select("SELECT * FROM student WHERE id=#{id}")

10. Student getStudentByID(int id);

11. }

第七步：建立Controller

StudentController.java

1. package com.example.Controller;

2.  

3. import com.example.Dao.StudentMapper;

4. import com.example.models.Student;

5. import org.springframework.beans.factory.annotation.Autowired;

6. import org.springframework.web.bind.annotation.RequestMapping;

7. import org.springframework.web.bind.annotation.RestController;

8.  

9. @RestController

10. public class StudentController {

11. @Autowired

12. private StudentMapper studentMapper;

13.  

14. @RequestMapping("/demo")

15. public Student get(){

16. Student student=studentMapper.getStudentByID(2);

17. return student;

18. }

19.  

20. @RequestMapping(value = "res")

21. public String df(){

22. return "Hello";

23. }

24. }

(注意這邊新建介面物件的時候會出錯誤提示，但是不影響正常執行，原因不明，如果有哪位知道怎麼解決請告知)

第八步：修改主程式

DemoApplication.java

1. package com.example.demo;

2.  

3. import org.mybatis.spring.annotation.MapperScan;

4. import org.springframework.boot.SpringApplication;

5. import org.springframework.boot.autoconfigure.SpringBootApplication;

6. import org.springframework.context.annotation.ComponentScan;

7. import org.springframework.transaction.annotation.EnableTransactionManagement;

8.  

9. @SpringBootApplication

10. @EnableTransactionManagement

11. @ComponentScan("com.example.Controller")

12. @MapperScan("com.example.Dao")

13.  

14. public class DemoApplication {

15.  

16. public static void main(String[] args) {

17. SpringApplication.run(DemoApplication.class, args);

18. }

19. }

第九步：最後還有個SpringBoot的配置檔案

application.properties

1. spring.datasource.url=jdbc:mysql://localhost:3306/world

2. spring.datasource.username=root

3. spring.datasource.password=a8996855439

4. spring.datasource.driverClassName=com.mysql.jdbc.Driver

5. mybatis.type-aliases-package=com.example.models

最後執行DemoApplication，在位址列輸入http://localhost:8080/demo

結果如下，就成功了
