上一期已经将后端的代码完成，目前开始做安卓端内容

编写Api接口，连接spring boot后端

package com.example.policyquery.api;

import com.example.policyquery.DataModel.Policy;

import java.util.List;
import retrofit2.Call;
import retrofit2.http.GET;
import retrofit2.http.Query;

public interface ApiService {

    @GET("/policyQuery/getAll")
    Call<List<Policy>> getAllPolicies();

    @GET("/policyQuery/query")
    Call<List<Policy>> queryPolicy(@Query("name") String name);
}

package com.example.policyquery.api;
import okhttp3.OkHttpClient;
import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;
import okhttp3.logging.HttpLoggingInterceptor;
public class RetrofitClient {
    private static Retrofit retrofit;
    private static final String BASE_URL = "http://172.20.10.3:8080/";
    public static Retrofit getRetrofitInstance() {
        if (retrofit == null) {
            // 创建 OkHttpClient 并添加日志拦截器
            OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
            HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
            loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
            httpClient.addInterceptor(loggingInterceptor);
            retrofit = new Retrofit.Builder()
                    .baseUrl(BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create())
                    .client(httpClient.build()) // 使用带有日志拦截器的 OkHttpClient
                    .build();
        }
        return retrofit;

    }
}
定义相关字段

package com.example.policyquery.DataModel;

public class Category {
    private String typeId;
    private String type;

    public String getTypeId() {
        return typeId;
    }

    public void setTypeId(String typeId) {
        this.typeId = typeId;
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }
}

package com.example.policyquery.DataModel;

import java.util.Date;

public class Policy {
    private Long id;
    private String name;
    private String type;
    private String category;
    private String range;
    private String document;
    private String form;
    private String organ;
    private Date viadata;
    private Date pubdata;
    private Date perdata;
    private String field;
    private String theme;
    private String keyword;
    private String superior;
    private String precursor;
    private String succeed;
    private String state;
    private String text;
    private String pdf;
    private String redundancy;
    private String rank;
    private String policykey;
    private String newrank;
    private String year;
    private String newkey;
    private String secondtheme;
    private Integer allsum;

    public Long getId() {
        return id;
    }

    public String getName() {
        return name;
    }

    public String getType() {
        return type;
    }

    public String getCategory() {
        return category;
    }

    public String getRange() {
        return range;
    }

    public String getDocument() {
        return document;
    }

    public String getForm() {
        return form;
    }

    public String getOrgan() {
        return organ;
    }

    public String getText() {
        return text;
    }
}
