最近，使用SpringBoot1.5.9搭建完成了个小项目，记录一下。

一、项目整体搭建

<modelVersion>4.0.0</modelVersion>
        <parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>

            <module>test-biz</module>
            <module>test-web</module>
        </modules>
    
        <properties>
            <java.version>1.8</java.version>
        </properties>
    
        <dependencies>
            <dependency>
                <groupId>com.zaxxer</groupId>
                <artifactId>HikariCP</artifactId>
            </dependency>
        </dependencies>

<modelVersion>4.0.0</modelVersion>
    
        
        <groupId>com.demo</groupId>
        <artifactId>test-web</artifactId>

        <parent>
            <groupId>com.demo</groupId>
            <artifactId>test-parent</artifactId>
            <version>0.0.1-SNAPSHOT</version>
        </parent>
    
        
        <dependencies>
        </dependencies>
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
            </plugins>
    
            <finalName>${profileActive}-test.demo.com</finalName>
            <resources>
                <resource>
                    <directory>src/main/resources</directory>
                    <filtering>true</filtering>
                    <includes>
                        <include>application.properties</include>
                        <include>application-${profileActive}.properties</include>
                    </includes>
                </resource>
                <resource>
                    <directory>src/main/resources/conf_${profileActive}</directory>
                    <filtering>true</filtering>
                </resource>
            </resources>
        </build>
    
        <profiles>
            <profile>
                <id>local</id>
                <activation>
                    <activeByDefault>true</activeByDefault>
                </activation>
                <properties>
                    <profileActive>local</profileActive>
                </properties>
            </profile>
            <profile>
                <id>dev</id>
                <properties>
                    <profileActive>dev</profileActive>
                </properties>
            </profile>
        </profiles>

一个父项目，多个子项目，注意项目间的依赖关系

二、数据库连接池配置

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
    spring.datasource.url=jdbc\:mysql\://localhost\:3306/test?zeroDateTimeBehavior=convertToNull&characterEncoding\=utf8
    spring.datasource.username=name
    spring.datasource.password=pw

三、swagger配置

<dependency>
                <groupId>io.springfox</groupId>
                <artifactId>springfox-swagger2</artifactId>
                <version>2.7.0</version>
                <exclusions>
                    <exclusion>
                        <artifactId>guava</artifactId>
                        <groupId>com.google.guava</groupId>
                    </exclusion>
                </exclusions>
            </dependency>
            <dependency>
                <groupId>io.springfox</groupId>
                <artifactId>springfox-swagger-ui</artifactId>
                <version>2.7.0</version>
            </dependency>

@Configuration
    @EnableSwagger2
    @Profile({ "local", "dev", "test" })
    public class SwaggerConfig {
        @Bean
        public Docket createRestApi() {
            return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).select()
                .apis(RequestHandlerSelectors.basePackage("com.demo.controller")) // Controller所在包(必须新建包)
                .paths(PathSelectors.any()).build();
        }
    
        private ApiInfo apiInfo() {
            return new ApiInfoBuilder().title("") // 标题
                .description("") // 描述
                .termsOfServiceUrl("") // 超链接
                .contact("") // 联系方式
                .version("1.0").build();
        }
    }

四、上传文件

五、参数校验

@Validated
    @Valid

@Slf4j
    @RestControllerAdvice
    public class ExceptionAdvice {
        /**
         * 验证异常
         * 
         * @param req
         * @param e
         * @return
         * @throws MethodArgumentNotValidException
         */
        @ExceptionHandler(value = MethodArgumentNotValidException.class)
        @ResponseBody
        public WebResponse handleMethodArgumentNotValidException(HttpServletRequest req, MethodArgumentNotValidException e)
            throws MethodArgumentNotValidException {
            WebResponse r = new WebResponse();
            BindingResult bindingResult = e.getBindingResult();
            String errorMesssage = "参数错误:";
    
            for (FieldError fieldError : bindingResult.getFieldErrors()) {
                errorMesssage += " " + fieldError.getDefaultMessage();
            }
            r.setCode(WebResponseStatus.WEB_STATUS_FAILED);
            r.setMessage(errorMesssage);
            log.info("MethodArgumentNotValidException", e);
            return r;
        }
    }

六、mybatis分页

Page page = PageHelper.startPage(paperQueryRequest.getPageDto().getPageNum(),
                    paperQueryRequest.getPageDto().getPageSize());
                String paperName = StringUtils.isEmpty(paperQueryRequest.getPaperName()) ? null
                    : "%" + paperQueryRequest.getPaperName() + "%";
                List<Paper> paperList = paperDao.getPaperList(paperName);
                int number =
                    (paperQueryRequest.getPageDto().getPageNum() - 1) * paperQueryRequest.getPageDto().getPageSize();
                List<PaperQueryResponse> paperQueryResponseList = convertPaper2PaperQueryResponse(paperList, number);
                PageInfo info = new PageInfo(page);
                info.setList(paperQueryResponseList);
    
    @UpdateProvider
    <![CDATA[ end_time > #{startTime} and end_time <= #{endTime} ]]>
