#  激活的环境
  profiles:
    active: dev
  application:
    name: reimbursementSystem
  servlet:
    multipart:

#      username: root
#      password: 123456
#      maxActive: 100
#      initialSize: 10
#   spring 默认的连接池
    url: jdbc:mysql://localhost:3306/test?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&useSSL=false&allowPublicKeyRetrieval=true
    username: root
    password: 123456
    driver-class-name: com.mysql.cj.jdbc.Driver

添加redis

redis:
    host: localhost
    port: 6379
    password: 123456
    database: 0

添加mybatis-plus

mybatis-plus:
  configuration:
    #在映射实体或者属性时，将数据库中表名和字段名中的下划线去掉，按照驼峰命名法映射
    map-underscore-to-camel-case: true
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
  global-config:
    db-config:
      id-type: ASSIGN_ID

添加Mybatis

mybatis:
  mapper-location: classpath:/mapper
    @Bean
    public Docket docket(){
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.group.reimbursement.controller"))
                .paths(PathSelectors.any())
                .build();
    }

    
    private ApiInfo apiInfo(){
        Contact contact = new Contact("张连勇、林良怀","https://blog.csdn.net/zly03?spm=1000.2115.3001.5343","lyzhang@163.com");
        return new ApiInfoBuilder()
                .title("发票管理系统")
                .version("1.0.2")
                .description("接口文档")
                .contact(contact)
                .build();
    }

}

添加静态资源过滤，如果有添加过滤器和拦截器，也需要在拦截器或者过滤器中放行相关的url*


    @Override
    protected void addResourceHandlers(ResourceHandlerRegistry registry) {
        log.info("开始进行静态资源映射...");
        registry.addResourceHandler("doc.html").addResourceLocations("classpath:/META-INF/resources/");
        registry.addResourceHandler("swagger-ui.html").addResourceLocations("classpath:/META-INF/resources/");
        registry.addResourceHandler("/webjars
@Configuration
public class MybatisPlusConfig {
    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor() {
        MybatisPlusInterceptor mybatisPlusInterceptor = new MybatisPlusInterceptor();
        mybatisPlusInterceptor.addInnerInterceptor(new PaginationInnerInterceptor());
        return mybatisPlusInterceptor;
    }
}

Response 常用的响应封装类


@Data
@ApiModel("统一返回类")
public class Response<T>  implements Serializable {

    
    @ApiModelProperty("状态码，统一200为成功")
    private Integer code;
    
    @ApiModelProperty("返回信息，错误信息")
    private String message;
    
    @ApiModelProperty("返回数据")
    private T data;
    
    @ApiModelProperty("动态数据")
    private Map<String, Object> map = new HashMap<>();

    public Response() {
    }

    public static <T> Response<T> successWithMessage(String message) {
        Response<T> r = new Response<>();
        r.message = message;
        r.data = null;
        r.code = HttpStatus.OK.value();
        return r;
    }

    public static <T> Response<T> success(T object) {
        Response<T> r = new Response<>();
        r.data = object;
        r.code = HttpStatus.OK.value();
        return r;
    }

    public static Response<String> buildJsonString(Object object) throws JsonProcessingException {
        String jsonString = toJsonString(object);
        return Response.success(jsonString);
    }

    private static String toJsonString(Object object) throws JsonProcessingException {

            ObjectMapper mapper = new ObjectMapper();
            DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
            mapper.setDateFormat(df);
            return mapper.writeValueAsString(object);
    }

    public static <T> Response<T> error(String message, int code) {
        Response<T> r = new Response<>();
        r.message = message;
        r.code = code;
        return r;
    }

    public static <T> Response<T> common(int code, String message) {
        Response<T> result = new Response<>();
        result.setCode(code);
        result.setMessage(message);
        return result;
    }

    public Integer getCode() {
        return code;
    }

    public void setCode(Integer code) {
        this.code = code;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public T getData() {
        return data;
    }

    public void setData(T data) {
        this.data = data;
    }

    public Response(Integer code, String message, T data) {
        this.code = code;
        this.message = message;
        this.data = data;
    }

}

BaseException 基础异常类BaseException


public class BaseException extends RuntimeException {

    private static final long serialVersionUID = 1L;

    
    private Integer code;
    
    private String message;

    public BaseException(String message) {
        this.message = message;
    }

    public BaseException(String message, Throwable cause, Integer code, String message1) {
        super(message, cause);
        this.code = code;
        this.message = message1;
    }

    public BaseException(String message, Integer code) {
        this.code = code;
        this.message = message;
    }
    public Integer getCode() {
        return code;
    }

    public void setCode(Integer code) {
        this.code = code;
    }

    @Override
    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

}
