Springboot 学习笔记 之 Day 3 JdbcTemplate thymeleaf 页面 做一个简易的bug系统

https://www.cnblogs.com/qianjinyan/p/10065160.html 

之前关于要做的系统的数据结构

今天实现连接mssql server，查询出所有buglist的效果

实现方法极其简单，如下图

　Bug类对象中列出字段

package com.jasmine.demo.bean;

public class Bug {

private long id;
private String pname;
private String crname;
private String crnum;
private String tasknum;
private String oname;
private String description;
private String rca;
private String solution;
private String developer;
private String tester;
private String creationdt;
private String updatedt;

public long getId() {
return id;
}

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

public String getPname() {
return pname;
}

public void setPname(String pname) {
this.pname = pname;
}

public String getCrname() {
return crname;
}

public void setCrname(String crname) {
this.crname = crname;
}

public String getCrnum() {
return crnum;
}

public void setCrnum(String crnum) {
this.crnum = crnum;
}

public String getTasknum() {
return tasknum;
}

public void setTasknum(String tasknum) {
this.tasknum = tasknum;
}

public String getOname() {
return oname;
}

public void setOname(String oname) {
this.oname = oname;
}

public String getDescription() {
return description;
}

public void setDescription(String description) {
this.description = description;
}

public String getRca() {
return rca;
}

public void setRca(String rca) {
this.rca = rca;
}

public String getSolution() {
return solution;
}

public void setSolution(String solution) {
this.solution = solution;
}

public String getDeveloper() {
return developer;
}

public void setDeveloper(String developer) {
this.developer = developer;
}

public String getTester() {
return tester;
}

public void setTester(String tester) {
this.tester = tester;
}

public String getCreationdt() {
return creationdt;
}

public void setCreationdt(String creationdt) {
this.creationdt = creationdt;
}

public String getUpdatedt() {
return updatedt;
}

public void setUpdatedt(String updatedt) {
this.updatedt = updatedt;
}

@Override
public String toString() {
return "Bug{" +
"id=" + id +
", pname='" + pname + '\'' +
", crname='" + crname + '\'' +
", crnum='" + crnum + '\'' +
", tasknum='" + tasknum + '\'' +
", oname='" + oname + '\'' +
", description='" + description + '\'' +
", rca='" + rca + '\'' +
", solution='" + solution + '\'' +
", developer='" + developer + '\'' +
", tester='" + tester + '\'' +
", creationdt='" + creationdt + '\'' +
", updatedt='" + updatedt + '\'' +
'}';
}

public Bug() {
super();
}

public Bug(long id, String pname, String crname, String crnum, String tasknum, String oname, String description, String rca, String solution, String developer, String tester, String creationdt, String updatedt) {
this.id = id;
this.pname = pname;
this.crname = crname;
this.crnum = crnum;
this.tasknum = tasknum;
this.oname = oname;
this.description = description;
this.rca = rca;
this.solution = solution;
this.developer = developer;
this.tester = tester;
this.creationdt = creationdt;
this.updatedt = updatedt;
}
}

BugService 接口中定义了增删查改等方法
具体实现是在对应的impl中

package com.jasmine.demo.service;

import com.jasmine.demo.bean.Bug;

import java.util.List;

public interface BugService {

List<Bug> findAll();

Bug findById(int id);

int create(String pname,String crname,String crnum, String tasknum, String oname, String description, String rca, String solution, String developer, String tester);

int update(long id, String crnum, String tasknum, String oname, String description, String rca, String solution, String developer, String tester);

int deleteByID(int id);

}

package com.jasmine.demo.service.impl;

import com.jasmine.demo.bean.Bug;
import com.jasmine.demo.jdbc.BugRowMapper;
import com.jasmine.demo.service.BugService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class BugServiceImpl implements BugService {

@Autowired
private JdbcTemplate jdbcTemplate;

@Override
public List<Bug> findAll() {

String sql = "SELECT BUG_ID,PROJECT_NAME,CR_NAME,BUG_CR_NUM,BUG_TASK_NUM,OBJECT_NAME,BUG_DESCRIPTION\n" +
",BUG_RCA,BUG_SOLUTION,B.EMPLOY_NAME DEVELOPER,A.EMPLOY_NAME TESTER,QA_CREATIONDT,QA_UPDATEDT,BUG_DELETED_FLAG\n" +
"FROM QA_BUGLIST\n" +
"JOIN QA_PROJECT ON BUG_PROJECT_ID = PROJECT_ID\n" +
"JOIN QA_CRTYPE ON CR_ID = BUG_CR_TYPE_ID\n" +
"JOIN QA_RTYPE ON OBJECT_ID = QA_TYPE_ID\n" +
"JOIN QA_EMPLOY A ON A.[EMPLOY_ID] = QA_TESTER_ID AND A.[EMPLOY_GROUP] = 1 ---表示测试\n" +
"JOIN QA_EMPLOY B ON B.[EMPLOY_ID] = QA_ASSIGNEE_ID AND B.[EMPLOY_GROUP] = 2 ---表示开发人员\n" +
"WHERE BUG_DELETED_FLAG =0 order by 1 desc";
List<Bug> bugs = jdbcTemplate.query(sql,new BugRowMapper() );
return bugs;

}

@Override
public Bug findById(int id) {
String sql = "SELECT BUG_ID,PROJECT_NAME,CR_NAME,isnull(BUG_CR_NUM,'') as BUG_CR_NUM,isnull(BUG_TASK_NUM,'') as BUG_TASK_NUM,OBJECT_NAME,isnull(BUG_DESCRIPTION,'') as BUG_DESCRIPTION\n" +
",isnull(BUG_RCA,'') as BUG_RCA,isnull(BUG_SOLUTION,'') as BUG_SOLUTION,B.EMPLOY_NAME DEVELOPER,A.EMPLOY_NAME TESTER,QA_CREATIONDT,QA_UPDATEDT,BUG_DELETED_FLAG\n" +
"FROM QA_BUGLIST\n" +
"JOIN QA_PROJECT ON BUG_PROJECT_ID = PROJECT_ID\n" +
"JOIN QA_CRTYPE ON CR_ID = BUG_CR_TYPE_ID\n" +
"JOIN QA_RTYPE ON OBJECT_ID = QA_TYPE_ID\n" +
"JOIN QA_EMPLOY A ON A.[EMPLOY_ID] = QA_TESTER_ID AND A.[EMPLOY_GROUP] = 1 ---表示测试\n" +
"JOIN QA_EMPLOY B ON B.[EMPLOY_ID] = QA_ASSIGNEE_ID AND B.[EMPLOY_GROUP] = 2 ---表示开发人员\n" +
"WHERE BUG_DELETED_FLAG =0 and BUG_ID = ?";
Bug bug = jdbcTemplate.queryForObject(sql,new BugRowMapper(),id);
return bug;
}

@Override
public int create(String pname,String crname,String crnum, String tasknum, String oname, String description, String rca, String solution, String developer, String tester) {
String sql ="INSERT QA_BUGLIST(BUG_PROJECT_ID,BUG_CR_TYPE_ID,BUG_CR_NUM,BUG_TASK_NUM,QA_TYPE_ID,BUG_DESCRIPTION,BUG_RCA,BUG_SOLUTION,QA_ASSIGNEE_ID,QA_TESTER_ID,QA_CREATIONDT,QA_UPDATEDT)\n" +
"VALUES(?,?,?,?,?,?,?,?,?,?,GETDATE(),GETDATE())";
return jdbcTemplate.update(sql,pname,crname,crnum,tasknum,oname,description,rca,solution,developer,tester);
}

@Override
public int update(long id, String crnum, String tasknum,  String description, String rca, String solution, String developer, String tester,String oname){
String sql = "update QA_BUGLIST set BUG_CR_NUM =?,BUG_TASK_NUM =?,BUG_DESCRIPTION=?,BUG_RCA=?,BUG_SOLUTION= ?,QA_UPDATEDT =getdate() where BUG_ID = ?";
System.out.println(sql);
return jdbcTemplate.update(sql,crnum,tasknum,description,rca,solution,id);
}

@Override
public int deleteByID(int id) {
String sql = "update QA_BUGLIST set BUG_DELETED_FLAG = 1,  BUG_DELETED_COMMENT = '逻辑删除' where BUG_ID = ?";
System.out.println(sql);
int count = jdbcTemplate.update(sql,id);
return count;
}
}

DB的配置写在application.xml中

启动类之后，跳转的所有页面，写在controller中，

启动后，打开连接，看到自己的数据

接下来要做的就是让页面好看一点，这样的数据看不清楚

 JdbcTemplate

thymeleaf

页面跳转等等，页面比较丑，还没做分页，搜寻条件也没有添加

1. 查看所有bug

2. 查看指定bug的详细信息

点击查看按钮后显示单个bug的信息

3. 删除单列bug信息，点击单个bug信息后面的删除按钮即可删除，删除之前最好有确定按钮用来提示，以免误删

4. 更新，我这边做在查看单个详细列表页面中，如上图，有信息更新按钮，点击后带入原先的参数跳转到更新页面，在新的页面进行更新，然后保存

5. 新增bug页面，在查看所有bug页面有新增按钮，点击进入如下页面，保存进行新增操作
