ssm框架首次搭建记录

首先放上整个ssm整合的基本结构：

整个spring所需要的jar包文件pom.xml：

在这个目录下，不然会报错。

接下来我把对应的什么转换器、拦截器、控制器、jpaDao、mybatiesDao格局一个例子供参考。

SqlMapper.xml(Mapper文件示例)：

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"  "http://mybatis.org/dtd/mybatis-3-mapper.dtd"><mapper namespace="cn.gson.springmvc.dao.mybaties.BookDao"><resultMap id="book" type="cn.gson.springmvc.entity.Book"><id property="id" column="id"/><result property="bookName" column="book_name"/><result property="bookPrice" column="book_price"/><result property="bookNum" column="book_num"/><result property="bookIsbn" column="book_isbn"/></resultMap><select id="getBookList" resultMap="book">select * from book where 1 = 1<choose><when test="bookName != null">and book_name like #{bookName}</when><otherwise><if test="bookPrice != null">and book_price like #{bookPrice}</if></otherwise></choose><if test="bookNum != null">and book_num = #{bookNum}</if></select></mapper>

JpTestController.java

package cn.gson.springmvc.controller;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping;import cn.gson.springmvc.dao.jpa.AccountDao;@Controller@RequestMapping("/jpa")public class JpTestController {@Autowiredprivate AccountDao acDao;@RequestMapping("/show")public String index(Model m){m.addAttribute("acList", acDao.findAll());return "jpa";}@RequestMapping("/add")public String add(Model m){m.addAttribute("acList", acDao.findAll());return "jpa";}}

DateConverter.java

package cn.gson.springmvc.converter;import java.text.ParseException;import java.text.SimpleDateFormat;import java.util.Date;import org.springframework.core.convert.converter.Converter;import org.springframework.util.StringUtils;public class DateConverter implements Converter<String, Date> {//这个转换器能转换的所有时间格式private String[] datePatterns = {"yyyy-MM-dd HH:mm:ss","yyyy-MM-dd HH:mm","yyyy-MM-dd","yyyy-MM"};@Overridepublic Date convert(String source) {Date date = null;if (!StringUtils.isEmpty(source)) {SimpleDateFormat sdf;for (String pattern : datePatterns) {sdf = new SimpleDateFormat(pattern);//在这里将source转换为date类型try {date = sdf.parse(source);break;} catch (ParseException e) {}}}return date;}public DateConverter() {// TODO Auto-generated constructor stub}public DateConverter(String... datePatterns) {this.datePatterns = datePatterns;}}

AccountDao.java

package cn.gson.springmvc.dao.jpa;import java.util.List;import org.springframework.data.repository.CrudRepository;import org.springframework.stereotype.Repository;import cn.gson.springmvc.entity.Account1;@Repositorypublic interface AccountDao extends CrudRepository<Account1, Integer> {List<Account1> findByAcnameAndGender(String acname,String gender);List<Account1> findByAcnameOrGenderOrderByIdDesc(String acname,String gender);List<Account1> findByDealsNotNull();}

BookDao.java

package cn.gson.springmvc.dao.mybaties;import java.util.List;import cn.gson.springmvc.entity.Book;public interface BookDao {int insertBook(Book b);List<Object> getBookList();int updateBook(Book b);int deleteBook(int i);List<Object> queryStudentAndBook();List<Object> queryBook();}

性能监控（拦截器 ）

Nature Interceptor.java

package cn.gson.springmvc.interceptor;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.web.servlet.ModelAndView;import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;/** * 性能监控 *  * @author gson * */public class NatureInterceptor extends HandlerInterceptorAdapter {private Long start;private String uri;@Overridepublic boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)throws Exception {start = System.currentTimeMillis();uri = request.getRequestURI();return true;}@Overridepublic void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,ModelAndView modelAndView) throws Exception {System.out.println(uri + ":请求执行完成耗时：" + (System.currentTimeMillis() - start));}@Overridepublic void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)throws Exception {System.out.println(uri + ":请求最终完成总耗时：" + (System.currentTimeMillis() - start));}}

大致的内容就是这样的了，期间虽然遇到了很多异常，但是通过调试和努力解决了问题。首先考虑是否是jar包冲突，其次考虑beanid是否重复，最后的话就注意数据库连接池的配置了。
