使用idea创建springboot项目

1. 创建项目

2.添加配置文件

• 日志配置logback-spring.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <include resource="org/springframework/boot/logging/logback/defaults.xml"/>
    <!--彩色日志输出格式-->
    <property name="CONSOLE_LOG_PATTERN"
              value="%clr(%d{yyyy-MM-dd HH:mm:ss.SSS}){faint} %clr(%level){blue} %clr(${PID}){magenta} %clr([%thread]){orange} %clr(%logger){cyan} %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}"/>
    <!--非彩色日志输出格式-->
    <property name="PATTERN"
              value="%clr(%d{yyyy-  MM-dd HH:mm:ss.SSS}){faint} %clr(%level){blue} %clr(${PID}){magenta} %clr([%thread]){orange} %clr(%logger){cyan} %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}"/>

    <!--dev文件路径：src同级目录logs,如果上级目录不存在会自动创建-->
    <property name="DEV_FILE_PATH" value="./logs"/>
    <!-- pro文件路径 -->
    <property name="PRO_FILE_PATH" value="./prod/logs"/>

    <!-- 控制台输出 -->
    <appender name="consoleAppender" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>${CONSOLE_LOG_PATTERN}</pattern>

    <!-- 按照每天生成输出日志文件 -->
    <appender name="fileAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <encoder>
            <!--格式化输出：%d表示日期，%thread表示线程，%-5level：级别从左显示五个字符宽度，%logger{36}：logger是class的全名,后面的数字代表限制最长的字符，%msg：日志消息，%n换行符-->
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
        </encoder>

            <!-- each file should be at most 10MB, keep 60 days worth of history, but at most 2GB -->
            <!--单个文件大小-->
            <maxFileSize>10MB</maxFileSize>
            <!--日志文件保留天数-->
            <maxHistory>60</maxHistory>
            <!--用来指定日志文件的上限大小，到了这个值就会删除旧日志-->
            <totalSizeCap>2GB</totalSizeCap>
        </rollingPolicy>
    </appender>

    <!-- 按照每天生成错误日志文件 -->
    <appender name="errorAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <!-- 此日志文件只记录ERROR级别的 -->
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">

        </encoder>
        <!--输出日志到src同级目录logs中的error.log文件中-->
        <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
            <!--基于大小和时间的轮转策略，当日志内容超出文件大小限制后，会自动生成一个文件来继续记录和重命名-->
            <fileNamePattern>${DEV_FILE_PATH}/error-%d{yyyy-MM-dd}.%i.log</fileNamePattern>
            <!-- each file should be at most 10MB, keep 60 days worth of history, but at most 2GB -->
            <maxFileSize>10MB</maxFileSize>

            <totalSizeCap>2GB</totalSizeCap>
        </rollingPolicy>
    </appender>

    <!--默认日志配置-->
    <springProfile name="default">

<!--            <appender-ref ref="errorAppender"/>-->
<!--        </root>-->
<!--    </springProfile>-->

</configuration>

• 项目配置application.yml

spring:
  profiles:
    active: default,dev
server:
  port: 8080

• 测试环境项目配置application-dev.yml

spring:
    datasource:
      type: com.zaxxer.hikari.HikariDataSource
      driver-class-name: com.mysql.cj.jdbc.Driver
      url: jdbc:mysql://localhost:3306/goodcc?useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=Asia/Shanghai
      username: root
      password: root
      hikari:
        minimum-idle: 5
        idle-timeout: 600000
        maximum-pool-size: 10
        auto-commit: true
        pool-name: MyHikariCP
        connection-timeout: 30000
        connection-test-query: SELECT 1
    jpa:
      # 关闭Hibernate的open-in-view
      open-in-view: false
      database-platform: org.hibernate.dialect.MySQL5InnoDBDialect
      hibernate:
        ddl-auto: update
      show-sql: true
      properties:
        hibernate:
          # 展示sql语句
          format_sql: true
          jdbc:
            time_zone: Asia/Shanghai

logging:
  level:

    # 展示sql语句查询参数
    org:
      hibernate:
        type:
          descriptor:
            sql:
              BasicBinder: trace

3. 修改依赖

<properties>
    <java.version>1.8</java.version>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <spring-boot.version>2.3.0.RELEASE</spring-boot.version>
</properties>

    <!-- Swagger End -->

</dependencies>

org.springframework.boot spring-boot-dependencies ${spring-boot.version} pom import ``` ## 4. 启动测试

5. 导入工具类

这边用到了swagger需要导入一下 Swagger2.java

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

/**
 * Swagger2配置类
 * 在与spring boot集成时，放在与Application.java同级的目录下。
 * 或者通过 @Import 导入配置
 */
@Configuration
@EnableSwagger2
public class Swagger2 {

    /**
     * 创建API应用
     * apiInfo() 增加API相关信息
     * 通过select()函数返回一个ApiSelectorBuilder实例,用来控制哪些接口暴露给Swagger来展现，
     * 本例采用指定扫描的包路径来定义指定要建立API的目录。
     *
     * @return
     */
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage(""))
                .paths(PathSelectors.any())
                .build();
    }

    /**
     * 创建该API的基本信息（这些基本信息会展现在文档页面中）
     * 访问地址：http://项目实际地址/swagger-ui.html
     *
     * @return
     */
    private ApiInfo apiInfo() {
        Contact contact = new Contact("1", "zhizhi", "zhizhi");
        return new ApiInfoBuilder()
                .title("Spring Boot中使用Swagger2构建RESTful APIs")
                .description("")
                .termsOfServiceUrl("")
                .contact(contact)
                .version("1.0")
                .build();
    }
}
