用SSM实现图书管理系统的图书类型管理模块用代码写出

以下是使用SSM框架实现图书管理系统的图书类型管理模块的代码示例：

1. 对应的Mapper接口：BookTypeMapper.java

package com.example.demo.mapper;

import com.example.demo.pojo.BookType;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;

import java.util.List;

@Mapper
public interface BookTypeMapper {
    int insert(BookType record);

    int insertSelective(BookType record);

    int updateByPrimaryKeySelective(BookType record);

    int updateByPrimaryKey(BookType record);

    int deleteByPrimaryKey(Integer id);

    List<BookType> selectAllBookTypes();

    BookType selectByPrimaryKey(Integer id);

    List<BookType> selectBookTypesByKeyword(@Param("keyword") String keyword);
}

2. 对应的Service接口：BookTypeService.java

package com.example.demo.service;

import com.example.demo.pojo.BookType;

import java.util.List;

public interface BookTypeService {
    int addBookType(BookType bookType);

    int updateBookType(BookType bookType);

    int deleteBookType(Integer id);

    List<BookType> getAllBookTypes();

    BookType getBookTypeById(Integer id);

    List<BookType> getBookTypesByKeyword(String keyword);
}

3. 对应的Service实现类：BookTypeServiceImpl.java

package com.example.demo.service.impl;

import com.example.demo.mapper.BookTypeMapper;
import com.example.demo.pojo.BookType;
import com.example.demo.service.BookTypeService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class BookTypeServiceImpl implements BookTypeService {
    @Autowired
    private BookTypeMapper bookTypeMapper;

    @Override
    public int addBookType(BookType bookType) {
        return bookTypeMapper.insertSelective(bookType);
    }

    @Override
    public int updateBookType(BookType bookType) {
        return bookTypeMapper.updateByPrimaryKeySelective(bookType);
    }

    @Override
    public int deleteBookType(Integer id) {
        return bookTypeMapper.deleteByPrimaryKey(id);
    }

    @Override
    public List<BookType> getAllBookTypes() {
        return bookTypeMapper.selectAllBookTypes();
    }

    @Override
    public BookType getBookTypeById(Integer id) {
        return bookTypeMapper.selectByPrimaryKey(id);
    }

    @Override
    public List<BookType> getBookTypesByKeyword(String keyword) {
        return bookTypeMapper.selectBookTypesByKeyword(keyword);
    }
}

4. 对应的Controller类：BookTypeController.java

package com.example.demo.controller;

import com.example.demo.pojo.BookType;
import com.example.demo.service.BookTypeService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.*;

import java.util.List;

@Controller
@RequestMapping("/bookType")
public class BookTypeController {
    @Autowired
    private BookTypeService bookTypeService;

    @GetMapping("/list")
    public String list(Model model) {
        List<BookType> bookTypes = bookTypeService.getAllBookTypes();
        model.addAttribute("bookTypes", bookTypes);
        return "bookType/list";
    }

    @GetMapping("/add")
    public String add(Model model) {
        model.addAttribute("bookType", new BookType());
        return "bookType/add";
    }

    @PostMapping("/add")
    public String add(BookType bookType) {
        bookTypeService.addBookType(bookType);
        return "redirect:/bookType/list";
    }

    @GetMapping("/update/{id}")
    public String update(@PathVariable("id") Integer id, Model model) {
        BookType bookType = bookTypeService.getBookTypeById(id);
        model.addAttribute("bookType", bookType);
        return "bookType/update";
    }

    @PostMapping("/update")
    public String update(BookType bookType) {
        bookTypeService.updateBookType(bookType);
        return "redirect:/bookType/list";
    }

    @GetMapping("/delete/{id}")
    public String delete(@PathVariable("id") Integer id) {
        bookTypeService.deleteBookType(id);
        return "redirect:/bookType/list";
    }

    @GetMapping("/search")
    public String search(@RequestParam(value = "keyword", required = false) String keyword, Model model) {
        List<BookType> bookTypes;
        if (keyword == null || keyword.equals("")) {
            bookTypes = bookTypeService.getAllBookTypes();
        } else {
            bookTypes = bookTypeService.getBookTypesByKeyword(keyword);
        }
        model.addAttribute("bookTypes", bookTypes);
        return "bookType/list";
    }
}

5. 对应的页面文件：list.html、add.html、update.html
