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：

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>

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 {
@Autowired
private 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"};

@Override
public Date convert(String source) {
Date date = null;
if (!StringUtils.isEmpty(source)) {
SimpleDateFormat sdf;
for (String pattern : datePatterns) {

//在这里将source转换为date类型
try {

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;

@Repository
public 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;

@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
throws Exception {
start = System.currentTimeMillis();
uri = request.getRequestURI();
return true;
}

@Override
public 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));
}

@Override
public 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。
