我正在创建需要调用SQL过程的应用程序。
我得到错误的参数是last,即第15个参数,contactID ..前五个参数也是唯一标识符,但它们设置正确..只是最后一个,即contactID在尝试时抛出异常将其设置为过程参数。
这是我的Java代码:
@SuppressWarnings({ "unchecked", "null" })
@Override
public JSONObject saveProductData(ProductsDataToSaveDTO ProductsDataToSaveDTO) throws SQLException {
String output = "";
Connection conn = null;
Statement sta = null;
String errorClassAndMethod = getErrorContainingClassAndMethod();
JSONObject jsonOutput = new JSONObject();
try {
Gson gson = new GsonBuilder().create();
String json = gson.toJson(ProductsDataToSaveDTO);
org.json.JSONObject jsonInput = new org.json.JSONObject(json);
conn = createConnection(jsonInput);
sta = conn.createStatement();
String SPsql = "{call SP_InsertUpdateAdvisoryBoxProductDetails (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)}";
PreparedStatement ps = conn.prepareStatement(SPsql);
System.out.println(jsonInput);
org.json.JSONArray productsList = (org.json.JSONArray) jsonInput.get("productsList");
ps.setString(1, ProductsDataToSaveDTO.getClientId());
ps.setString(2, ProductsDataToSaveDTO.getDivisionId());
ps.setString(3, ProductsDataToSaveDTO.getClientRoleId());
ps.setString(4, ProductsDataToSaveDTO.getUserID());
ps.setString(5, ProductsDataToSaveDTO.getUserLoginDetailId());
for (ProductsList productsListBO : ProductsDataToSaveDTO.getProductsList()) {
if (productsListBO.getProductCategory().equalsIgnoreCase("AOV")) {
ps.setString(6, productsListBO.getProductSituation());
String output2 = productsListBO.getProductSituation();
ps.setString(7, productsListBO.getProductCategory());
ps.setString(8, productsListBO.getProductSubcategory());
ps.setString(9, productsListBO.getProviderName());
ps.setString(10, productsListBO.getProductName());
ps.setString(11, productsListBO.getServiceProvider());
ps.setString(12, productsListBO.getPolicyNumber());
ps.setString(13,productsListBO.getProductClosed());
ps.setString(14, productsListBO.getNameFirstInsured());
ps.setString(15, productsListBO.getContactID());
}
ResultSet rs = ps.executeQuery();
while (rs.next()) {
output = rs.getString(1);
jsonOutput.put("status", output);
}
}
} catch (Exception e) {
output = e.toString();
e.printStackTrace();
String errorMessageAndClassWithMethod = getErrorContainingClassAndMethod();
throw new SpringAppRuntimeException(errorMessageAndClassWithMethod + e.toString());
} finally {
if (sta != null) {
conn.close();
}
if (conn != null) {
conn.close();
}
}
return jsonOutput;
}
当我运行我的服务时,我收到错误, “发生了应用程序运行时异常。[ClassName.saveProductData中的错误:com.microsoft.sqlserver.jdbc.SQLServerException:从字符串转换为uniqueidentifier时转换失败。]”
我应该在代码中进行哪些更改才能成功运行它?
答案 0 :(得分:1)
因此,根据您的评论,我将其添加为答案
1)ps.setString(15, productsListBO.getContactID());"
2)检查您的程序SP_InsertUpdateAdvisoryBoxProductDetails
的第15个参数是@ProductSituation NVARCHAR(10)
3)这真的是一个标识符字段,varchar是否与contactID的长度相匹配?改变10说100并测试。
4)我还认为你在参数中设置值的顺序(基于方法名称)和程序参数的顺序是不同的。仔细检查并纠正它
