代码生成器

最近再次阅读了MyBatis-Plus的官方文档，发现已经实现了代码生成器的绝大部分内容，但还没达到能直接生成一个项目的水平，因此我想在此基础上继续封装：

1、Controller层

该层包括四种接口：分页查询，单个信息查询，添加/修改，删除（可配置成逻辑删除）

2、基于MyBatis-Plus的分页插件

@Configuration
public class MyBatisPlusConfig {
    @Bean
    public PaginationInterceptor paginationInterceptor() {
        PaginationInterceptor paginationInterceptor = new PaginationInterceptor();
        // 设置请求的页面大于最大页后操作， true调回到首页，false 继续请求  默认false
        // paginationInterceptor.setOverflow(false);
        // 设置最大单页限制数量，默认 500 条，-1 不受限制
        // paginationInterceptor.setLimit(500);
        return paginationInterceptor;
    }
}

3、异常处理包

4、全局异常处理器

@ControllerAdvice
public class GlobalExceptionHandler {

    @ResponseBody
    @ExceptionHandler(ServiceException.class)
    public Result exceptionHandler(ServiceException e) {
        return Result.exception(e);
    }
}

5、拦截器

@Component
public class WebAppInterceptor extends HandlerInterceptorAdapter {

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        return super.preHandle(request, response, handler);
    }
}

@Configuration
public class WebAppConfig extends WebMvcConfigurerAdapter {

    @Autowired
    private WebAppInterceptor webAppInterceptor;

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(webAppInterceptor);
    }
}

6、返回结果再次封装（还需完善）

/

@Getter
@Setter
public class Result<T> {

    private Integer code;

    private String message;

    private T data;

    private Result(Integer code, String message, T data) {
        this.code = code;
        this.message = message;
        this.data = data;
    }

    private Result(Integer code, String message) {
        this.code = code;
        this.message = message;
    }

    public static <T> Result<T> ok(T data) {
        return new Result<>(200, "success", data);
    }

    public static <T> Result<T> ok() {
        return new Result<>(200, "success");
    }

    public static <T> Result<T> error(String message) {
        return new Result<>(500, message);
    }

    public static <T> Result<T> exception(ServiceException e) {
        return new Result<>(e.getCode(), e.getMessage());
    }
}
