java怎么将字符串EncryptParam(httpHeaders={pkgName=joy, sysLang=CN}, pageNumber=1, pageSize=10)解析成json数据

在Java中，你可以使用`org.json`库来将这种形式的字符串转换为JSON对象。首先，你需要创建一个对应的Java对象来映射这个字符串，然后使用`JSONObject`类来构建JSON。假设我们有如下的类结构：

public class EncryptParams {
    private Map<String, String> httpHeaders;
    private intpageNumber;
    private int pageSize;

    // getters and setters for each field
    public Map<String, String> getHttpHeaders() { return httpHeaders; }
    public void setHttpHeaders(Map<String, String> httpHeaders) { this.httpHeaders = httpHeaders; }

    public int getPageNumber() { return pageNumber; }
    public void setPageNumber(int pageNumber) { this.pageNumber = pageNumber; }

    public int getPageSize() { return pageSize; }
    public void setPageSize(int pageSize) { this.pageSize = pageSize; }
}

// 创建httpHeaders的map
Map<String, String> headersMap = new HashMap<>();
headersMap.put("pkgName", "joy");
headersMap.put("sysLang", "CN");

// 现在可以构造EncryptParams对象并转化为JSON
String jsonString = "{\"httpHeaders\": {" + headersMap.toString().replace("{", "").replace("}", "") + "}, \"pageNumber\": 1, \"pageSize\": 10}";
EncryptParams encryptParams = new EncryptParams();
encryptParams.setHttpHeaders(headersMap);
encryptParams.setPageNumber(1);
encryptParams.setPageSize(10);

JSONObject jsonObject = new JSONObject();
jsonObject.put("httpHeaders", encryptParams.getHttpHeaders());
jsonObject.put("pageNumber", encryptParams.getPageNumber());
jsonObject.put("pageSize", encryptParams.getPageSize());

System.out.println(jsonObject.toString());

这样就得到了一个包含给定信息的JSON字符串。
