springboot vue front-end and back-end interface test tree node adding function method

Test platform development based on springboot vue

1. The append method of the front-end Tree tree control

There is a append method under the elementUI tree control, which can be used To append a child node to a node in the Tree.

At present, we have completed the interface of the tree list. We can output what is in the incoming data in the append method.

console.log('传入的node：' + JSON.stringify(data))

Click on the top-level default node, F12 to view the console,

You can see:

Formatting it is actually the tree structure of the entire node. Which node is clicked, the data content is all the node data under this node.

But in fact, I only need the data of the currently clicked node. I don’t need to care about the children under this node. However, considering that the amount of data is not large, I just pass it to the backend in its entirety.

2. Back-end implementation of node new interface

The function I want to implement is to click the add button of which node, which is to add the child node of this node, for example:

Since the front-end can get the data of the current node, the idea of ​​adding a new interface is also there:

Get the data set creation time and creation time of the current node passed by the front-end. The update time set is pos, which is the position order of the newly added child node among the sibling nodes. The level of the child node is set, which is the level of the current node. 1set The parent node of the child node, which is the node of the current incoming interface. idset adds the name of the node, = last insert

1. controller layer

Add the corresponding controller method:

@PostMapping("/add")
  public Result addNode(@RequestBody ApiModule node) {
      try {
          System.out.println(node);
          Long nodeId = apiModuleService.addNode(node);
          return Result.success(nodeId);
      } catch (Exception e) {
          return Result.fail(e.toString());
      }
  }

2.service layer

Implement addNode method:

public Long addNode(ApiModule node) {
        node.setCreateTime(new Date());
        node.setUpdateTime(new Date());
        double pos = getNextLevelPos(node.getProjectId(), node.getLevel(), node.getId());
        node.setPos(pos);
        node.setLevel(node.getLevel() + 1);
        node.setParentId(node.getId());
        node.setName("ceshi111");
        apiModuleDAO.insert(node);
        return node.getId();
    }

This is implemented according to the above ideas. SetName is temporarily replaced with a fixed value. First, check whether the new interface can be implemented normally.

Pos processing here is a little more troublesome. This represents the position order of the newly added node, so I extracted it and added a new method to implement getNextLevelPos:

private double getNextLevelPos(Long projectId, int level, Long nodeId) {
      // 查询项目下，同parentId下，所有节点
      QueryWrapper<ApiModule> queryWrapper = new QueryWrapper<>();
      queryWrapper.eq("projectId", projectId)
                  .eq("level", level + 1)
                  .eq("parentId", nodeId)
                  .orderByDesc("pos");
      List<ApiModule> apiModules = apiModuleDAO.selectList(queryWrapper);
      if (!CollectionUtil.isEmpty(apiModules)) {
          // 不为空，获取最新的同级结点 pos 再加 1，作为下一个
          return apiModules.get(0).getPos() + 1;
      } else {
          // 否则就是当前父节点里的第一个子结点，pos 直接为 1
          return 1;
      }
  }

Under the query item, the same as parentId, all node data, pay attention to the query conditions here.

.eq("level", level 1), the current level 1 is used as the level of the child node.eq("parentId", nodeId), the current node is used as the parent node

Then judge and query it As a result, if the list is not empty, the pos of the latest child node plus 1 is returned as the position of the next child node.

Otherwise, the newly added node is the first child node in the current parent node, and 1 is returned directly as the pos value.

3. Front-end and back-end joint debugging

The front-end writes the interface, and then calls the interface on the page.

Call the interface, add a success prompt, and then refresh the tree list.

The function is normal. A child node with the fixed name "ceshi111" is added under the corresponding node, and the tree is refreshed to display the latest data.

4. Edit the node name

The above is completed, which proves that there is no big problem with the function. Now we only need to solve the problem of editing the node name. Decided to use dialog box to solve the problem.

Click the Add button to open the dialog box, where you can enter the node name and save it. This dialog box is also available for editing scenes.

In the project management function, I have already used the dialog box once. I directly copied the relevant code and modified it.

corresponds to return:

There will be 2 buttons in the dialog box: Cancel and Save. When you click the save button, different methods will be called depending on whether it is new or modified.

1. Open the dialog box

Modify the append method, and you need to open the dialog box when you click the new button.

There is another important point, because new nodes need to be passed in data, and now the actual new operation is the handleNodeAdd method. So you need to save the data when opening the dialog box.

So, create a new field currentNode in return: {}:

Assign data to currentNode in the append method:

Here this.dialogStatus = 'create' is to display the dialog box.

2. Add a new node

Enter the node name in the dialog box, click Save, and then call the handleNodeAdd method to request the backend interface.

Because the node name passed to the backend is entered by us, so here this.currentNode.name = this.form.nodeName.

#Give a prompt after the request is successful, and then clear the form to avoid displaying the last content after opening the dialog box.

3. Test

To test whether the function is normal, I delete the node under project id=3.

Add a new test node:

Function is normal.
