java 地址匹配工具类

Java地址匹配工具类

在日常的开发中，常常会遇到需要对地址进行匹配的需求，比如验证用户输入的地址是否合法，提取地址中的省市区信息等。为了方便地处理这些需求，我们可以编写一个Java地址匹配工具类来实现这些功能。本文将介绍如何编写一个简单的Java地址匹配工具类，并提供代码示例。

工具类设计

首先，我们需要确定工具类的设计。考虑到地址的结构一般为省、市、区（县）、街道、门牌号等多级结构，我们可以定义一个Address类来表示地址，其中包含省、市、区、街道和门牌号等属性。

接下来，我们定义一个AddressMatcher类作为地址匹配工具类，该类提供了一系列静态方法来处理地址相关的操作。其中包括验证地址是否合法、提取地址的省市区信息等功能。

类图设计

下面是Address类和AddressMatcher类的类图：

classDiagram
    class Address {
        - String province
        - String city
        - String district
        - String street
        - String number
        + Address(String province, String city, String district, String street, String number)
        + getProvince(): String
        + setProvince(String province): void
        + getCity(): String
        + setCity(String city): void
        + getDistrict(): String
        + setDistrict(String district): void
        + getStreet(): String
        + setStreet(String street): void
        + getNumber(): String
        + setNumber(String number): void
    }

    class AddressMatcher {
        + isAddressValid(String address): boolean
        + extractProvince(String address): String
        + extractCity(String address): String
        + extractDistrict(String address): String
        + extractStreet(String address): String
        + extractNumber(String address): String
    }

    Address "1" -- "1" AddressMatcher

代码实现

下面是Address类的代码实现：

public class Address {
    private String province;
    private String city;
    private String district;
    private String street;
    private String number;

    public Address(String province, String city, String district, String street, String number) {
        this.province = province;
        this.city = city;
        this.district = district;
        this.street = street;
        this.number = number;
    }

    public String getProvince() {
        return province;
    }

    public void setProvince(String province) {
        this.province = province;
    }

    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }

    public String getDistrict() {
        return district;
    }

    public void setDistrict(String district) {
        this.district = district;
    }

    public String getStreet() {
        return street;
    }

    public void setStreet(String street) {
        this.street = street;
    }

    public String getNumber() {
        return number;
    }

    public void setNumber(String number) {
        this.number = number;
    }
}

接下来是AddressMatcher类的代码实现：

public class AddressMatcher {
    public static boolean isAddressValid(String address) {
        // 验证地址是否合法的逻辑
        // ...
        return true;
    }

    public static String extractProvince(String address) {
        // 提取地址的省份信息的逻辑
        // ...
        return "省份";
    }

    public static String extractCity(String address) {
        // 提取地址的城市信息的逻辑
        // ...
        return "城市";
    }

    public static String extractDistrict(String address) {
        // 提取地址的区县信息的逻辑
        // ...
        return "区县";
    }

    public static String extractStreet(String address) {
        // 提取地址的街道信息的逻辑
        // ...
        return "街道";
    }

    public static String extractNumber(String address) {
        // 提取地址的门牌号信息的逻辑
        // ...
        return "门牌号";
    }
}

使用示例

下面是使用AddressMatcher类的示例代码：

public class Main {
    public static void main(String[] args) {
        String address = "北京市朝阳区XXX街道XXX号";
        if (AddressMatcher.isAddressValid(address)) {
            String province = AddressMatcher.extractProvince(address);
            String city = AddressMatcher.extractCity(address);
            String district = AddressMatcher.extractDistrict(address);
            String street = AddressMatcher.extractStreet
