基于SSM框架学生管理系统的实现

这是我一年前做的项目的，算是SSM框架入门的实例，maven管理工具所用到的仓库私服为阿里云的仓库。整个项目的目录：jdbc.properties是对数据库信息的配置：#mysql version database settingjdbc.driver=com.mysql.jdbc.Driverjdbc.username=rootjdbc.password=jdbc.url=jdbc

jdbc.properties是对数据库信息的配置：

#mysql version database setting
jdbc.driver=com.mysql.jdbc.Driver
jdbc.username=root
jdbc.password=
jdbc.url=jdbc\:mysql\://127.0.0.1\:3306/test?useUnicode=true&amp;characterEncoding=UTF-8

StudentMapper.xml，SQL语句编写的地方：

MyBatis的Dao基类:

package com.HelloWorld.orm.mybatis;

import java.io.Serializable;
import java.util.List;

import org.mybatis.spring.support.SqlSessionDaoSupport;

/**
 * MyBatis的Dao基类
 * @author 
 */
public class MyBatisDao extends SqlSessionDaoSupport{
	
	public void save(String key, Object object) {

	public void delete(String key, Object object) {

	public <T> T get(String key, Object params) {
		return (T) getSqlSession().selectOne(key, params);

	}

	public <T> List<T> getList(String key, Object params) {

entity实体类：

package com.HelloWorld.examples.base.entity;

public class Student {
	private Integer id;
	private String name;
	private float chinese;
	private float  math;
	private float english;
	public Integer getId() {

}

Service层

package com.HelloWorld.examples.base.service;

import java.io.Serializable;
import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;


import com.HelloWorld.examples.base.entity.Student;

@Service
public class StudentService {
	@Autowired

	}
	
	public Student getStudent(Serializable id){
		return myBatisDao.get("StudentMapper.selectByPrimaryKey",id);
	}
	
	public void save(Student student){
		   
		if(student.getId()==null)
			myBatisDao.save("StudentMapper.insert", student);
		else
			myBatisDao.save("StudentMapper.update",student);
	}

	
	public void delete(Serializable id){
		myBatisDao.delete("StudentMapper.delete", id);
	}
}

controller层：

package com.HelloWorld.examples.base.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import com.HelloWorld.examples.base.entity.Student;
import com.HelloWorld.examples.base.service.StudentService;

@Controller
@RequestMapping("/student")
public class StudentController {
	@Autowired
	private StudentService studentService;
	
	@RequestMapping(method = RequestMethod.GET)
	public String list(Model model){
		model.addAttribute("list", studentService.getStudent());
		return "base/student_list";
	}
	
	@RequestMapping(value="/new", method = RequestMethod.GET)
	public String create(Model model, Student student){
		model.addAttribute("entity",student);
		return "base/student_new";
	}
	
	@RequestMapping(value="/edit/{id}", method = RequestMethod.GET)
	public String edit(Model model, @PathVariable Integer id){
		model.addAttribute("entity", studentService.getStudent(id));

	@RequestMapping(value="/save", method = RequestMethod.POST)
	public String save(Model model, Student student){

函数实现越通用越好？来看看 Byzer-LLM 的 Function Implementation 带来的编程思想大变化...

前言Function Calling 是 OpenAI 首先提出来的一个非常有用的功能，实现了大模型对函数的调用能力。Byzer-LLM 给开源模型也带来了 Function Calling 实现。在这个基础上，我们还拓展了 Respond With Class 功能，允许大模型输出标准的Python对象，进步控制了大模型的输出能力。这两个能力参看：给开源大模型带来Function Callin.
