房间支付方式管理相关代码

需要完成三个接口的实现：

  • 查询全部支付方式列表
  • 保存或更新支付方式
  • 根据ID删除支付方式

controller层

java 复制代码 
package com.nie.lease.web.admin.controller.apartment;


import com.baomidou.mybatisplus.core.conditions.query.LambdaQueryWrapper;
import com.nie.lease.common.result.Result;
import com.nie.lease.model.entity.PaymentType;
import com.nie.lease.web.admin.service.PaymentTypeService;
import io.swagger.v3.oas.annotations.Operation;
import io.swagger.v3.oas.annotations.tags.Tag;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import java.util.List;


@Tag(name = "支付方式管理")
@RequestMapping("/admin/payment")
@RestController
public class PaymentTypeController {

    @Autowired
    private PaymentTypeService paymentTypeService;

    @Operation(summary = "查询全部支付方式列表")
    @GetMapping("list")
    public Result<List<PaymentType>> listPaymentType() {
        List<PaymentType> list = paymentTypeService.list();
        return Result.ok(list);
    }

    @Operation(summary = "保存或更新支付方式")
    @PostMapping("saveOrUpdate")
    public Result saveOrUpdatePaymentType(@RequestBody PaymentType paymentType) {
        paymentTypeService.saveOrUpdate(paymentType);
        return Result.ok();
    }

    @Operation(summary = "根据ID删除支付方式")
    @DeleteMapping("deleteById")
    public Result deletePaymentById(@RequestParam Long id) {
        paymentTypeService.removeById(id);
        return Result.ok();
    }

}

service层

java 复制代码 
package com.nie.lease.web.admin.service;

import com.nie.lease.model.entity.PaymentType;
import com.baomidou.mybatisplus.extension.service.IService;

/**
* @author liubo
* @description 针对表【payment_type(支付方式表)】的数据库操作Service
* @createDate 2023-07-24 15:48:00
*/
public interface PaymentTypeService extends IService<PaymentType> {

}

房间租期管理相关代码

需要完成三个接口的实现

  • 查询全部租期列表
  • 保存或更新租期信息
  • 根据ID删除租期

controller层

java 复制代码 
package com.nie.lease.web.admin.controller.apartment;


import com.nie.lease.common.result.Result;
import com.nie.lease.model.entity.LeaseTerm;
import com.nie.lease.web.admin.service.LeaseTermService;
import io.swagger.v3.oas.annotations.Operation;
import io.swagger.v3.oas.annotations.tags.Tag;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import java.util.List;

@Tag(name = "租期管理")
@RequestMapping("/admin/term")
@RestController
public class LeaseTermController {

    @Autowired
    private LeaseTermService leaseTermService;

    @GetMapping("list")
    @Operation(summary = "查询全部租期列表")
    public Result<List<LeaseTerm>> listLeaseTerm() {
        List<LeaseTerm> list = leaseTermService.list();
        return Result.ok(list);
    }

    @PostMapping("saveOrUpdate")
    @Operation(summary = "保存或更新租期信息")
    public Result saveOrUpdate(@RequestBody LeaseTerm leaseTerm) {
        leaseTermService.saveOrUpdate(leaseTerm);
        return Result.ok();
    }

    @DeleteMapping("deleteById")
    @Operation(summary = "根据ID删除租期")
    public Result deleteLeaseTermById(@RequestParam Long id) {
        leaseTermService.removeById(id);
        return Result.ok();
    }
}

service层

java 复制代码 
package com.nie.lease.web.admin.service;

import com.nie.lease.model.entity.LeaseTerm;
import com.baomidou.mybatisplus.extension.service.IService;

/**
* @author liubo
* @description 针对表【lease_term(租期)】的数据库操作Service
* @createDate 2023-07-24 15:48:00
*/
public interface LeaseTermService extends IService<LeaseTerm> {

}

标签管理相关代码

需要完成三个接口的实现

  • （根据类型）查询标签列表
  • 新增或修改标签信息
  • 根据id删除标签信息

编写自定义Converter用于枚举类型装换

java 复制代码 
package com.nie.lease.web.admin.custom.converter;

import com.nie.lease.model.enums.ItemType;
import org.springframework.core.convert.converter.Converter;
import org.springframework.stereotype.Component;


@Component
public class StringToItemTypeConverter implements Converter<String, ItemType> {

    @Override
    public ItemType convert(String code) {

        ItemType[] values = ItemType.values();
        for (ItemType itemType : values) {
            if (itemType.getCode().equals(Integer.valueOf(code))){
                return itemType;
            }
        }

        throw new IllegalArgumentException("code"+code+"非法");
    }


}

注册我们写的Converter

java 复制代码 
package com.nie.lease.web.admin.custom.config;

import com.nie.lease.web.admin.custom.converter.StringToItemTypeConverter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.format.FormatterRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class WebMvcConfiguration implements WebMvcConfigurer {

    @Autowired
    private StringToItemTypeConverter stringToItemTypeConverter;
    @Override
    public void addFormatters(FormatterRegistry registry) {
        registry.addConverter(this.stringToItemTypeConverter);
    }
    
}

但是像这样写的话 我们需要写好多个这样的类 所以我们采用工厂设计模式

自定义ConverterFactory类

java 复制代码 
package com.nie.lease.web.admin.custom.converter;

import com.nie.lease.model.enums.BaseEnum;
import org.springframework.core.convert.converter.Converter;
import org.springframework.core.convert.converter.ConverterFactory;
import org.springframework.stereotype.Component;

@Component
public class StringToBaseEnumConverterFactory implements ConverterFactory<String, BaseEnum> {
    @Override
    public <T extends BaseEnum> Converter<String, T> getConverter(Class<T> targetType) {
        return new Converter<String, T>() {
            @Override
            public T convert(String code) {
                T[] enumConstants = targetType.getEnumConstants();
                for (T enumConstant : enumConstants) {
                    if (enumConstant.getCode().equals(Integer.parseInt(code))) {
                        return enumConstant;
                    }
                }
                throw new IllegalArgumentException("code"+code+"非法");
            }
        };
    }
}

注册ConverterFactory类

java 复制代码 
package com.nie.lease.web.admin.custom.config;

import com.nie.lease.web.admin.custom.converter.StringToBaseEnumConverterFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.format.FormatterRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class WebMvcConfiguration implements WebMvcConfigurer {

    @Autowired
    private StringToBaseEnumConverterFactory stringToBaseEnumConverterFactory;
    @Override
    public void addFormatters(FormatterRegistry registry) {
        registry.addConverterFactory(this.stringToBaseEnumConverterFactory);
    }

}

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import java.util.List;

@Tag(name = "标签管理")
@RestController
@RequestMapping("/admin/label")
public class LabelController {

    @Autowired
    private LabelInfoService labelInfoService;
    @Operation(summary = "（根据类型）查询标签列表")
    @GetMapping("list")
    public Result<List<LabelInfo>> labelList(@RequestParam(required = false) ItemType type) {
        LambdaQueryWrapper<LabelInfo> labelInfoLambdaQueryWrapper = new LambdaQueryWrapper<>();
        labelInfoLambdaQueryWrapper.eq(type!=null,LabelInfo::getType,type);
        List<LabelInfo> list = labelInfoService.list(labelInfoLambdaQueryWrapper);
        return Result.ok(list);
    }

    @Operation(summary = "新增或修改标签信息")
    @PostMapping("saveOrUpdate")
    public Result saveOrUpdateLabel(@RequestBody LabelInfo labelInfo) {
        labelInfoService.saveOrUpdate(labelInfo);
        return Result.ok();
    }

    @Operation(summary = "根据id删除标签信息")
    @DeleteMapping("deleteById")
