ssm框架搭建

阿新 • • 發佈：2020-09-06

一：環境準備

jdk：java version "1.8.0_251"

Tomcat：tomacat8

Maven：Apache Maven 3.6.3

二，新建maven工程

工程建立完成，

2，搭建專案結構

專案結構如下

3，Customer.java

package com.liam.pojo;

public class Customer {

    /**
     * 客戶持久層
     */
    private Integer id;
    private String userName;
    private String jobs;
    
 
private String phone;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    
 
public String getJobs() {
        return jobs;
    }

    public void setJobs(String jobs) {
        this.jobs = jobs;
    }

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

}

4,CustomerDao

package com.liam.dao;


 
import com.liam.pojo.Customer;

public interface CustomerDao {
    /**
     * 根據id 查詢客戶資訊
     * @param id
     * @return
     */
    public Customer findCustomerById(Integer id);
}

5,CustomerService

package com.liam.service;

import com.liam.pojo.Customer;

public interface CustomerService {
    public Customer findCustomerById(Integer id);
}

6,CustomerServiceImpl

package com.liam.service.impl;

import com.liam.dao.CustomerDao;
import com.liam.pojo.Customer;
import com.liam.service.CustomerService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

@Service
@Transactional
public class CustomerServiceImpl implements CustomerService {

    @Autowired
    private CustomerDao customerDao;
    @Override
    public Customer findCustomerById(Integer id) {
        return this.customerDao.findCustomerById(id);
    }
}

7,CustomerController

package com.liam.controller;

import com.liam.pojo.Customer;
import com.liam.service.CustomerService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class CustomerController {
    @Autowired
    private CustomerService customerService;

    @RequestMapping("/findCustomerById")
    public String findCustomerById(Integer id, Model model){
        Customer customer = customerService.findCustomerById(id);
        model.addAttribute("customer",customer);
        return "customer";
    }
}

17,執行結果

總結：

1，網上的參考資料比較多，主要參考了：

https://www.cnblogs.com/wanson/articles/9998829.html

2，在我第一次搭建的時候，使用的是tomacat10，結果一直出現

解決無果，換用tomacat8，未出現上面的問題。

2，

java.lang.IllegalArgumentException: No enum constant org.apache.ibatis.type.JdbcType.Intege

mybatis配置的jdbcType型別要是大寫的，檢查了mybatis的配置檔案，果然是這個問題

3，

Could not get JDBC Connection; nested exception isorg.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory

參考此連結：

https://blog.csdn.net/weixin_41955327/article/details/82286309

報錯之前為 userName -> user，對應的

4,

There is no setter for property named 'dd_valueId' in 'class com.manager.pojo.DataDictionary'的錯誤解決方法

mybatis 對映檔案和 Bean應該對應一致。

5，

使用Idea部署SSM專案後，訪問路徑為url:8080/專案名_war_exploded的解決方案

在tomcat配置頁的Deployment下，修改Application context為/，即可直接使用url:8080訪問專案主頁。或者任意你想要的路徑，

6，

Result Maps collection does not contain value for 錯誤

當時未新增resultMap 資料型別，parameterType 型別也選的不正確。按照上面正確的配置即可

7，

java.sql.SQLException: The server time zone value '???ú±ê×??±??' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.

錯誤資訊翻譯—— java.sql.SQLException: 伺服器時區值'?? u±e×??±??未被識別或代表多個時區。如果希望利用時區支援，必須配置伺服器或JDBC驅動程式(通過serverTimezone配置屬性)，以使用更特殊的時區值。

解決方法：JDBC連線的URL後面加上serverTimezone = GMT，如果需要使用GMT + 8時區，需要寫成GMT％2B8。

追加上後面這些

8，使用Idea構建springmvc框架，出現no bean named ‘cacheManager’ is defined 錯誤。

9，整個工程參考連結
