SpringApplication app = new SpringApplication(DemoApplication.class); + app.setBannerMode(Mode.OFF); + app.run(args); +} +``` + + + +## 全局配置文件 + +在src/main/resources目录下，Spring Boot提供了一个名为application.properties的全局配置文件，可对一些默认配置的配置值进行修改。 + +> 附：[application.properties中可配置所有官方属性](https://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html) + +### 自定义属性值 + +Spring Boot允许我们在application.properties下自定义一些属性，比如： + +``` +mrbird.blog.name=mrbird's blog +mrbird.blog.title=Spring Boot +``` + + + +定义一个BlogProperties Bean，通过`@Value("${属性名}")`来加载配置文件中的属性值： + +``` +@Component +public class BlogProperties { + + @Value("${mrbird.blog.name}") + private String name; + + @Value("${mrbird.blog.title}") + private String title; + + // get,set略 +} +``` + + + +编写IndexController，注入该Bean： + +``` +@RestController +public class IndexController { + @Autowired + private BlogProperties blogProperties; + + @RequestMapping("/") + String index() { + return blogProperties.getName()+"——"+blogProperties.getTitle(); + } +} +``` + + + +启动项目，访问[http://localhost:8080](http://localhost:8080/)，页面显示如下： + +![QQ截图20171130112735.png](https://mrbird.cc/img/QQ%E6%88%AA%E5%9B%BE20171130112735.png) + +在属性非常多的情况下，也可以定义一个和配置文件对应的Bean： + +``` +@ConfigurationProperties(prefix="mrbird.blog") +public class ConfigBean { + private String name; + private String title; + // get,set略 +} +``` + + + +通过注解`@ConfigurationProperties(prefix="mrbird.blog")`指明了属性的通用前缀，通用前缀加属性名和配置文件的属性名一一对应。 + +除此之外还需在Spring Boot入口类加上注解`@EnableConfigurationProperties({ConfigBean.class})`来启用该配置： + +``` +@SpringBootApplication +@EnableConfigurationProperties({ConfigBean.class}) +public class Application { + + public static void main(String[] args) { + SpringApplication.run(Application.class, args); + } +} +``` + + + +之后便可在IndexController中注入该Bean，并使用了： + +``` +@RestController +public class IndexController { + @Autowired + private ConfigBean configBean; + + @RequestMapping("/") + String index() { + return configBean.getName()+"——"+configBean.getTitle(); + } +} +``` + + + +### 属性间的引用 + +在application.properties配置文件中，各个属性可以相互引用，如下： + +``` +mrbird.blog.name=mrbird's blog +mrbird.blog.title=Spring Boot +mrbird.blog.wholeTitle=${mrbird.blog.name}--${mrbird.blog.title} +``` + + + +## 自定义配置文件 + +除了可以在application.properties里配置属性，我们还可以自定义一个配置文件。在src/main/resources目录下新建一个test.properties: + +``` +test.name=KangKang +test.age=25 +``` + + + +定义一个对应该配置文件的Bean： + +``` +@Configuration +@ConfigurationProperties(prefix="test") +@PropertySource("classpath:test.properties") +@Component +public class TestConfigBean { + private String name; + private int age; + // get,set略 +} +``` + + + +注解`@PropertySource("classpath:test.properties")`指明了使用哪个配置文件。要使用该配置Bean，同样也需要在入口类里使用注解`@EnableConfigurationProperties({TestConfigBean.class})`来启用该配置。 + +## 通过命令行设置属性值 + +在运行Spring Boot jar文件时，可以使用命令`java -jar xxx.jar --server.port=8081`来改变端口的值。这条命令等价于我们手动到application.properties中修改（如果没有这条属性的话就添加）server.port属性的值为8081。 + +如果不想项目的配置被命令行修改，可以在入口文件的main方法中进行如下设置： + +``` +public static void main(String[] args) { + SpringApplication app = new SpringApplication(Application.class); + app.setAddCommandLineProperties(false); + app.run(args); +} +``` + + + +## 使用xml配置 + +虽然Spring Boot并不推荐我们继续使用xml配置，但如果出现不得不使用xml配置的情况，Spring Boot允许我们在入口类里通过注解`@ImportResource({"classpath:some-application.xml"})`来引入xml配置文件。 + +## Profile配置 + +Profile用来针对不同的环境下使用不同的配置文件，多环境配置文件必须以`application-{profile}.properties`的格式命，其中`{profile}`为环境标识。比如定义两个配置文件： + +- application-dev.properties：开发环境 + + ``` + server.port=8080 + ``` + +- application-prod.properties：生产环境 + + ``` + server.port=8081 + ``` + +至于哪个具体的配置文件会被加载，需要在application.properties文件中通过`spring.profiles.active`属性来设置，其值对应`{profile}`值。 + +如：`spring.profiles.active=dev`就会加载application-dev.properties配置文件内容。可以在运行jar文件的时候使用命令`java -jar xxx.jar --spring.profiles.active={profile}`切换不同的环境配置。 \ No newline at end of file diff --git

+Druid是一个关系型数据库连接池，是阿里巴巴的一个开源项目，地址：https://github.com/alibaba/druid。Druid不但提供连接池的功能，还提供监控功能，可以实时查看数据库连接池和SQL查询的工作情况。 + +### 配置Druid依赖 + +Druid为Spring Boot项目提供了对应的starter： + +``` + + com.alibaba +

+``` +#SpringBoot在2.0版本之后已经弃用server.context-path，而代替为server.servlet.context-path +server: + servlet: + context-path: /web + port: 8003 + +spring: + datasource: + druid: + # 数据库访问配置, 使用druid数据源 + type:

+关于Druid的更多说明，可查看官方wiki——[https://github.com/alibaba/druid/wiki/%E5%B8%B8%E8%A7%81%E9%97%AE%E9%A2%98](https://github.com/alibaba/druid/wiki/常见问题) + +## 使用MyBatis + +使用的库表： + +``` +CREATE TABLE "SCOTT"."STUDENT" ( + "SNO" VARCHAR2(3 BYTE) NOT NULL , + "SNAME" VARCHAR2(9 BYTE) NOT NULL , + "SSEX" CHAR(2 BYTE) NOT NULL +); + +INSERT INTO "SCOTT"."STUDENT" VALUES ('001', 'KangKang', 'M '); +INSERT INTO "SCOTT"."STUDENT" VALUES ('002', 'Mike', 'M '); +INSERT INTO "SCOTT"."STUDENT" VALUES ('003', 'Jane', 'F '); +``` + + + +创建对应实体： + +``` +public class Student implements Serializable{ + private static final long serialVersionUID = -339516038496531943L; + private String sno; + private String name; + private String sex; + // get,set略 +} +``` + + + +创建一个包含基本CRUD的StudentMapper： + +``` +public interface StudentMapper { + int add(Student student); + int update(Student student); + int deleteByIds(String sno); + Student queryStudentById(Long id); +} +``` + + + +StudentMapper的实现可以基于xml也可以基于注解。 + +### 使用注解方式 + +继续编辑StudentMapper： + +``` +@Component +@Mapper +public interface StudentMapper { + @Insert("insert into student(sno,sname,ssex) values(#{sno},#{name},#{sex})") + int add(Student student); + + @Update("update student set sname=#{name},ssex=#{sex} where sno=#{sno}") + int update(Student student); + + @Delete("delete from student where sno=#{sno}") + int deleteBysno(String sno); + + @Select("select * from student where sno=#{sno}") + @Results(id = "student",value= { + @Result(property = "sno", column = "sno", javaType = String.class), + @Result(property = "name", column = "sname", javaType = String.class), + @Result(property = "sex", column = "ssex", javaType = String.class) + }) + Student queryStudentBySno(String sno); +``` + + + +简单的语句只需要使用@Insert、@Update、@Delete、@Select这4个注解即可，动态SQL语句需要使用@InsertProvider、@UpdateProvider、@DeleteProvider、@SelectProvider等注解。具体可参考MyBatis官方文档：http://www.mybatis.org/mybatis-3/zh/java-api.html。 + +### 使用xml方式 + +使用xml方式需要在application.yml中进行一些额外的配置： + +``` +mybatis: + # type-aliases扫描路径 + # type-aliases-package: + # mapper xml实现扫描路径 + mapper-locations: classpath:mapper/*.xml + property: + order: BEFORE +``` + + + +## 测试 + +接下来编写Service： + +``` +public interface StudentService { + int add(Student student); + int update(Student student); + int deleteBysno(String sno); + Student queryStudentBySno(String sno); +} +``` + + + +实现类： + +``` +@Service("studentService") +public class StudentServiceImp implements StudentService{ + @Autowired + private StudentMapper studentMapper; + + @Override + public int add(Student student) { + return this.studentMapper.add(student); + } + + @Override + public int update(Student student) { + return this.studentMapper.update(student); + } + + @Override + public int deleteBysno(String sno) { + return this.studentMapper.deleteBysno(sno); + } + + @Override + public Student queryStudentBySno(String sno) { + return this.studentMapper.queryStudentBySno(sno); + } +} +``` + + + +编写controller： + +``` +@RestController +public class TestController { + + @Autowired + private StudentService studentService; + + @RequestMapping( value = "/querystudent", method = RequestMethod.GET) + public Student queryStudentBySno(String sno) { + return this.studentService.queryStudentBySno(sno); + } +} +``` + +完整的项目目录如下图所示：
