Question

我有一个使用来自Lombok的@ slf4j注释的Spring应用程序，但是我用它登录的所有内容都没有显示在控制台中。

我的应用程序包括以下库 SLF4J-API-1.7.21 JCL-过SLF4J-1.7.21 龙目-1.16.10

我记录的所有东西都被传递给NOPLogger（无操作记录器），它完全按照它应该做的......没有！

我是否需要在某处配置工厂才能使用实际记录内容的记录器？

我想，添加slf4j-api是不够的，你还需要正确实现APi。

添加此功能将起作用：

Loader::BasicData Loader::TestEdgeCollapse(float vertices[], int vertexLength, int indices[], int indexLength, float texCoords[], int texCoordLength, float normals[], int normalLength)
{
    // Mesh type
    typedef OpenMesh::TriMesh_ArrayKernelT<>   OPMesh;
    // Decimater type
    typedef OpenMesh::Decimater::DecimaterT< OPMesh > OPDecimater;
    // Decimation Module Handle type
    typedef OpenMesh::Decimater::ModQuadricT< OPMesh >::Handle HModQuadric;

    OPMesh mesh;
    std::vector<OPMesh::VertexHandle> vhandles;
    int iteration = 0;
    for (int i = 0; i < vertexLength; i += 3)
    {
        vhandles.push_back(mesh.add_vertex(OpenMesh::Vec3f(vertices[i], vertices[i + 1], vertices[i + 2])));
        if (texCoords != nullptr)
            mesh.set_texcoord2D(vhandles.back(),OpenMesh::Vec2f(texCoords[iteration * 2], texCoords[iteration * 2 + 1]));
        if (normals != nullptr)
            mesh.set_normal(vhandles.back(), OpenMesh::Vec3f(normals[i], normals[i + 1], normals[i + 2]));
        iteration++;
    }

    for (int i = 0; i < indexLength; i += 3)
        mesh.add_face(vhandles[indices[i]], vhandles[indices[i + 1]], vhandles[indices[i + 2]]);

    OPDecimater decimater(mesh);
    HModQuadric hModQuadric;
    decimater.add(hModQuadric);
    decimater.module(hModQuadric).unset_max_err();
    decimater.initialize();
    //decimater.decimate(); // without this, everything is fine as expect.
    mesh.garbage_collection();

    int verticesSize = mesh.n_vertices() * 3;

    int normalSize = mesh.n_vertices() * 3;
    if(mesh.has_vertex_normals())
        newNormals = new float[normalSize];

    Loader::BasicData data;

    int index = 0;
    for (v_it = mesh.vertices_begin(); v_it != mesh.vertices_end(); ++v_it)
    {
        OpenMesh::Vec3f &point = mesh.point(*v_it);
        newVertices[index * 3] = point[0];
        newVertices[index * 3 + 1] = point[1];
        newVertices[index * 3 + 2] = point[2];
        if (mesh.has_vertex_texcoords2D())
        {
            auto &tex = mesh.texcoord2D(*v_it);
            newTexCoords[index * 2] = tex[0];

            newNormals[index * 3] = normal[0];
            newNormals[index * 3 + 1] = normal[1];
            newNormals[index * 3 + 2] = normal[2];
        }
        index++;
    }
    index = 0;

    for (f_it = mesh.faces_begin(); f_it != mesh.faces_end(); ++f_it)
        for (fv_it = mesh.fv_ccwiter(*f_it); fv_it.is_valid(); ++fv_it)
