SpringBoot系列第3篇整合技术

整合Junit

只需要使用SpringBootTest一个注解就可以完成

@SpringBootTest
class SpringApplicationTest {
    @Autowired
    private BookService bookService;
    @Test
    public void testSave() {
        bookService.save();
    }
}

如果测试类不在SpringBoot启动类的包或子包中，需要设置classes

@SpringBootTest(classes = SpringBootApplicaiton.class)

整合Mybatis

首先需要导入相关的依赖，依赖包括mybaits，mysql，druid连接池

<!--数据库框架-->
<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>2.2.0</version>
</dependency>

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <scope>runtime</scope>
</dependency>

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid</artifactId>
    <version>1.1.22</version>
</dependency>

然后设置数据源相关的参数

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/ssm_db?serverTimezone=GMT
    username: root
    password: 123456
    type: com.alibaba.druid.pool.DruidDataSource

dao层需要添加@Mapper注解

@Mapper
public interface BookDao {
    @Select("select * from tbl_book")
    public List<Book> getAll();
}

SpringBoot整合SSM

整合案例使用了之前的SSM整合，所有资源文件可以从SSM项目中获取，SpringBoot整合项目只进行了少部分的修改

1.首先需要导入相关的依赖

<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.5.0</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.example</groupId>
    <artifactId>ssm</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>ssm</name>
    <properties>
        <java.version>1.8</java.version>
    </properties>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <!--排除tomcat-->
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-tomcat</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

        <!--添加jetty-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-jetty</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

        <!--自定义封装警告-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-configuration-processor</artifactId>
            <optional>true</optional>
        </dependency>

        <!--数据库框架-->
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>2.2.0</version>
        </dependency>

        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <scope>runtime</scope>
        </dependency>

        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.1.22</version>
        </dependency>
    </dependencies>

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

2.然后不需要之前SSM整合中的config目录中，需要在dao中添加@Mapper接口

@Mapper
public interface BookDao {
    @Insert("insert into tbl_book (type, name, description) values(#{type}, #{name}, #{description})")
    public int save(Book book);

    @Update("update tbl_book set type=#{type}, name=#{name}, description=#{description} where id=#{id}")
    public int update(Book book);

    @Delete("delete from tbl_book where id =#{id}")
    public int delete(Integer id);

    @Select("select * from tbl_book where id= #{id}")
    public Book getById(Integer id);

    @Select("select * from tbl_book")
    public List<Book> getAll();
}

3.需要在application.yml文件中配置相关的设置

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/ssm_db?serverTimezone=GMT
    username: root
    password: 123456
    type: com.alibaba.druid.pool.DruidDataSource
server:
  port: 8081

4.最后一步将前端文件复制到resources中的static目录中，如果想要直接使用端口访问，则需要将page文件夹中的index.html文件复制到static目录中
