线缆库存管理程序

前言：

    朋友是作线缆生意的，想要一个进销存管理可是网上的现成的不太试用，功能太多操做繁琐，对于以米为单位的线缆，库存不能简单的加减。须要定制一个功能精简的进销存。

    项目源码地址：https://github.com/Gengry/zlxsC

    数据库文件在data目录下，最新的导入便可12开头的是17年的文件，01开头的是18年的当时只是用月日标识没有加年。

技术选型：

    以前用过一点spring boot可是项目不是本身搭建的，最近在看spring boot就用他吧。前端试用的zheng admin ui（https://github.com/shuzheng/zhengAdmin）是基于bootstarp的，函数库Jquery，数据表格 bootstrap table，select2，jquery-confirm，zheng common的baseservice，mybatis，mybatis generator， druid，mysql，maven。

    spring boot集成druid文档（https://github.com/alibaba/druid/tree/master/druid-spring-boot-starter）。我并无使用spring boot druid starter，而且关闭了spring boot datasource auto configuration。

@SpringBootApplication(exclude={DataSourceAutoConfiguration.class})

配置datasource。

package com.zhonglianxs.erp.cpw.config;

import com.alibaba.druid.pool.DruidDataSource;
import com.github.pagehelper.PageHelper;

import javax.sql.DataSource;
import java.sql.SQLException;
import java.util.Properties;

//生命为java配置类

//开启spring事物支持
@EnableTransactionManagement
//配置mybatis mapper扫描
@MapperScan(value = "com.zhonglianxs.erp.cpw.mapper")
public class DataBaseConfiguration implements EnvironmentAware{

    private Environment environment;
    private RelaxedPropertyResolver propertyResolver;
    @Override
    public void setEnvironment(Environment environment) {
        this.environment = environment;
        this.propertyResolver = new RelaxedPropertyResolver(environment,"spring.datasource.");
    }

    //配置druidDataSource
    @Bean(name = "druidDataSource" ,initMethod = "init",destroyMethod = "close")
    public DruidDataSource dataSource(){
        DruidDataSource druidDataSource = new DruidDataSource();
        druidDataSource.setDriverClassName(propertyResolver.getProperty("driverClassName"));
        druidDataSource.setUrl(propertyResolver.getProperty("url"));
        druidDataSource.setUsername(propertyResolver.getProperty("username"));
        druidDataSource.setPassword(propertyResolver.getProperty("password"));
        druidDataSource.setMaxActive(20);
        druidDataSource.setInitialSize(1);
        druidDataSource.setMaxWait(60000);
        druidDataSource.setTimeBetweenEvictionRunsMillis(60000);

        druidDataSource.setMaxOpenPreparedStatements(20);
        druidDataSource.setValidationQuery("SELECT 'x'");
        return druidDataSource;
    }

    //配置mybatis sqlsessionFactory
    @Bean public SqlSessionFactory sqlSessionFactory(@Qualifier("druidDataSource") DataSource dataSource) throws Exception {
        SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
        sqlSessionFactoryBean.setDataSource(dataSource);
        //配置mybatis分页插件
        Properties props = new Properties();
        props.setProperty("offsetAsPageNum", "false");
        props.setProperty("rowBoundsWithCount", "true");
        props.setProperty("pageSizeZero", "false");
        props.setProperty("reasonable", "false");
        props.setProperty("params", "pageNum=pageNum;pageSize=pageSize;count=countSql;reasonable=reasonable;pageSizeZero=pageSizeZero");
        props.setProperty("supportMethodsArguments","false");
        props.setProperty("autoRuntimeDialect","true");

        PageInterceptor pageInterceptor = new PageInterceptor();
        pageInterceptor.setProperties(props);
        sqlSessionFactoryBean.setPlugins(new Interceptor[]{pageInterceptor});
        //配置mybatis xml文件路径
        PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
        sqlSessionFactoryBean.setMapperLocations(resolver.getResources("classpath*:com/zhonglianxs/erp/cpw/mapping/*.xml"));
        return sqlSessionFactoryBean.getObject();
    }
    
    //配置spring 事物管理器
    @Bean public PlatformTransactionManager transactionManager() throws SQLException {
        return new DataSourceTransactionManager(dataSource());
    }

}

发现启动后获取不到mybatis中的定义的方法，查了查都是说mapper名字和xml名字定义不一致什么的，可是检查后发现是一致的，maven package后打开打包文件，发现其中没有resource目录下的xml文件。应该是maven配置问题。参考https://www.cnblogs.com/pixy/p/4798089.html

对pom.xml加入以下配置

<resources>
            <resource>
                <directory>src/main/resources</directory>
				<includes>
					<include>**/*.properties</include>
					<include>**/*.xml</include>
					<include>**/**</include>
				</includes>
                <filtering>false</filtering>
            </resource>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                </includes>
                <filtering>false</filtering>
            </resource>
        </resources>

配置spring mvc messageConConverter（https://my.oschina.net/u/3714931/blog/1594680）。

配置 jsp，一开始若是不部署在tomcat下解析不了jsp，由于spring boot没有自动集成解析jsp的包。参考http://tengj.top/2017/03/13/springboot5/

pom.xml文件中配置

<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-tomcat</artifactId>
			<scope>provided</scope>
		</dependency>
		<dependency>
			<groupId>org.apache.tomcat.embed</groupId>
			<artifactId>tomcat-embed-jasper</artifactId>
			<!--<scope>provided</scope>-->
		</dependency>
		<dependency>
			<groupId>javax.servlet</groupId>
			<artifactId>jstl</artifactId>
			<version>1.2</version>
		</dependency>

配置jsp开发模式不须要重启直接生效

server.jsp-servlet.init-parameters.development=true

没有作权限控制。
