*************************** APPLICATION FAILED TO START *************************** Description: Field jedisPool in com.mt.mtip.preclient.point.data.DataClient required a bean of type 'redis.clients.jedis.util.Pool' that could not be found. The injection point has the following annotations: - @org.springframework.beans.factory.annotation.Autowired(required=true) Action: Consider defining a bean of type 'redis.clients.jedis.util.Pool' in your configuration.

这是一个Spring Boot应用程序启动失败的错误提示，原因是在DataClient类中需要一个名为jedisPool的类型为redis.clients.jedis.util.Pool的Bean，但是在配置中找不到这个Bean。需要你在配置文件中定义一个名为jedisPool的Bean，并且类型为redis.clients.jedis.util.Pool，这样就可以解决错误了。

*** [app] Error 1

As an AI language model, I cannot provide a specific answer without more context. However, "Error 1" in software development usually indicates that the build or compilation process has failed due to a critical error. This error message can appear when compiling source code, installing software packages, or executing scripts. The cause of this error can vary depending on the application, programming language, and development environment. Developers can usually find more information about the error by examining the build log or error message output.

C语言参数 封装IDispatch*入参 并返回

在 C 语言中，使用 IDispatch 接口封装对象可以实现对象的方法调用和属性访问。在函数中，我们可以通过传递 IDispatch* 类型的指针参数来访问和修改对象的属性和方法。函数也可以通过返回 IDispatch* 类型的指针来返回一个封装对象的实例。

以下是一个示例代码，演示了如何使用 IDispatch 接口封装对象来传递参数并返回对象：

#include <stdio.h>
#include <windows.h>

IDispatch* create_object() {
    CLSID clsid;
    HRESULT hr = CLSIDFromProgID(L"Excel.Application", &clsid);
    if (FAILED(hr)) {
        return NULL;
    }

    IDispatch* pExcel = NULL;
    hr = CoCreateInstance(&clsid, NULL, CLSCTX_LOCAL_SERVER, IID_IDispatch, (void**) &pExcel);
    if (FAILED(hr)) {
        return NULL;
    }

    return pExcel;
}

void set_cell_value(IDispatch* pWorksheet, int row, int col, LPWSTR value) {
    DISPID dispId;
    BSTR propName = SysAllocString(L"Cells");
    VARIANT result;
    VariantInit(&result);

    DISPPARAMS params = { 0 };
    VARIANT args[2];
    args[0].vt = VT_I4;
    args[0].lVal = row;
    args[1].vt = VT_I4;
    args[1].lVal = col;
    params.cArgs = 2;
    params.rgvarg = args;

    HRESULT hr = pWorksheet->GetIDsOfNames(IID_NULL, &propName, 1, LOCALE_SYSTEM_DEFAULT, &dispId);
    if (FAILED(hr)) {
        return;
    }

    hr = pWorksheet->Invoke(dispId, IID_NULL, LOCALE_SYSTEM_DEFAULT, DISPATCH_PROPERTYGET, &params, &result, NULL, NULL);
    if (FAILED(hr)) {
        return;
    }

    IDispatch* pCell = result.pdispVal;
    if (pCell == NULL) {
        return;
    }

    propName = SysAllocString(L"Value");
    VARIANTARG valueArg;
    valueArg.vt = VT_BSTR;
    valueArg.bstrVal = SysAllocString(value);
    DISPID putDispId;
    hr = pCell->GetIDsOfNames(IID_NULL, &propName, 1, LOCALE_SYSTEM_DEFAULT, &putDispId);
    if (FAILED(hr)) {
        return;
    }

    params.cArgs = 1;
    params.rgvarg = &valueArg;
    hr = pCell->Invoke(putDispId, IID_NULL, LOCALE_SYSTEM_DEFAULT, DISPATCH_PROPERTYPUT, &params, NULL, NULL, NULL);
    if (FAILED(hr)) {
        return;
    }

    SysFreeString(propName);
    VariantClear(&result);
}

int main() {
    IDispatch* pExcel = create_object();
    if (pExcel == NULL) {
        printf("Failed to create Excel instance.\n");
        return 1;
    }

    BSTR propName = SysAllocString(L"ActiveWorkbook");
    DISPID dispId;
    HRESULT hr = pExcel->GetIDsOfNames(IID_NULL, &propName, 1, LOCALE_SYSTEM_DEFAULT, &dispId);
    if (FAILED(hr)) {
        printf("Failed to get ActiveWorkbook property.\n");
        return 1;
    }

    VARIANT result;
    VariantInit(&result);
    hr = pExcel->Invoke(dispId, IID_NULL, LOCALE_SYSTEM_DEFAULT, DISPATCH_PROPERTYGET, NULL, &result, NULL, NULL);
    if (FAILED(hr)) {
        printf("Failed to invoke ActiveWorkbook property.\n");
        return 1;
    }

    IDispatch* pWorkbook = result.pdispVal;
    if (pWorkbook == NULL) {
        printf("Failed to get workbook instance.\n");
        return 1;
    }

    propName = SysAllocString(L"ActiveSheet");
    hr = pWorkbook->GetIDsOfNames(IID_NULL, &propName, 1, LOCALE_SYSTEM_DEFAULT, &dispId);
    if (FAILED(hr)) {
        printf("Failed to get ActiveSheet property.\n");
        return 1;
    }

    VariantClear(&result);
    hr = pWorkbook->Invoke(dispId, IID_NULL, LOCALE_SYSTEM_DEFAULT, DISPATCH_PROPERTYGET, NULL, &result, NULL, NULL);
    if (FAILED(hr)) {
        printf("Failed to invoke ActiveSheet property.\n");
        return 1;
    }

    IDispatch* pWorksheet = result.pdispVal;
    if (pWorksheet == NULL) {
        printf("Failed to get worksheet instance.\n");
        return 1;
    }

    set_cell_value(pWorksheet, 1, 1, L"Hello");
    set_cell_value(pWorksheet, 1, 2, L"World");

    pWorksheet->Release();
    pWorkbook->Release();
    pExcel->Release();
    return 0;
}

在这个示例中，我们使用 IDispatch 接口封装了一个 Excel.Application 对象，并使用 create_object 函数来创建对象实例。我们还定义了 set_cell_value 函数来设置单元格的值。该函数接受一个 IDispatch* 类型的指针参数，该参数指向一个 Excel.Worksheet 对象。在函数内部，我们使用 GetIDsOfNames 和 Invoke 函数来访问单元格对象，并使用 SetProperty 函数来设置单元格的值。最后，我们在 main 函数中调用 set_cell_value 函数来设置单元格的值，并释放对象实例。
