The detailed introduction of mybatis implementation of reading tree structure data is as follows:

Table structure

CREATE TABLE `lscrm_function_privilege` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT COMMENT &#39;编号&#39;,
`create_id` varchar(30) NOT NULL DEFAULT &#39;sys&#39;,
`update_id` varchar(30) NOT NULL DEFAULT &#39;sys&#39;,
`create_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT &#39;创建时间&#39;,
`update_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT &#39;修改时间&#39;,
`validity` tinyint(3) unsigned NOT NULL DEFAULT &#39;1&#39; COMMENT &#39;有效性 1.有效 0. 无效&#39;,
`code` varchar(50) NOT NULL DEFAULT &#39;&#39; COMMENT &#39;编码&#39;,
`function_name` varchar(50) NOT NULL DEFAULT &#39;&#39; COMMENT &#39;名称&#39;,
`parent_id` tinyint(3) unsigned NOT NULL DEFAULT &#39;0&#39; COMMENT &#39;父节点&#39;,
`is_leaf_node` tinyint(3) unsigned NOT NULL DEFAULT &#39;1&#39; COMMENT &#39;是否叶子节点(叶子结点 就是度为0的结点 就是没有子结点的结点),在添加子节点时,需要将parent_id is_leaf_node 设置成0&#39;,
`sub_system_id` int(10) unsigned NOT NULL DEFAULT &#39;0&#39; COMMENT &#39;所属子系统&#39;,
`is_hidden` tinyint(3) unsigned NOT NULL DEFAULT &#39;0&#39; COMMENT &#39;UI是否隐藏,ui上不展示&#39;,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=22 DEFAULT CHARSET=utf8 COMMENT=&#39;子code 按照父code 来创建\r\n如: customer.add&#39;;

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

How does session hijacking work and how can you mitigate it in PHP? Apr 06, 2025 am 12:02 AM

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

What are Enumerations (Enums) in PHP 8.1? Apr 03, 2025 am 12:05 AM

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
