ssm+shiro框架搭建笔记（3）

配置mybatis

(1). 配置Spring.xml。

文件添加一下配置信息：

<!-- 数据库连接配置 -->
<import resource="spring-mybatis.xml"/>

(2).添加配置spring-mybatis.xml文件。

文件配置信息：

<!-- 引入属性文件 -->
<context:property-placeholder location="classpath:config.properties" />
<!-- 配置数据源 -->
<bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
init-method="init" destroy-method="close">
<property name="url" value="${jdbc_url}" />
<property name="username" value="${jdbc_username}" />
<property name="password" value="${jdbc_password}" />
<!-- 初始化连接大小 -->
<property name="initialSize" value="0" />
<!-- 连接池最大使用连接数量 -->
<property name="maxActive" value="20" />
<!-- 连接池最大空闲 -->
<property name="maxIdle" value="20" />
<!-- 连接池最小空闲 -->
<property name="minIdle" value="0" />
<!-- 获取连接最大等待时间 -->
<property name="maxWait" value="60000" />
<!-- <property name="poolPreparedStatements" value="true" /> <property
name="maxPoolPreparedStatementPerConnectionSize" value="33" /> -->
<property name="validationQuery" value="${validationQuery}" />
<property name="testOnBorrow" value="false" />
<property name="testOnReturn" value="false" />
<property name="testWhileIdle" value="true" />
<!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 -->
<property name="timeBetweenEvictionRunsMillis" value="60000" />
<!-- 配置一个连接在池中最小生存的时间，单位是毫秒 -->
<property name="minEvictableIdleTimeMillis" value="25200000" />
<!-- 打开removeAbandoned功能 -->
<property name="removeAbandoned" value="true" />
<!-- 1800秒，也就是30分钟 -->
<property name="removeAbandonedTimeout" value="1800" />
<!-- 关闭abanded连接时输出错误日志 -->
<property name="logAbandoned" value="true" />
<!-- 监控数据库 -->
<!-- <property name="filters" value="stat" /> -->
<property name="filters" value="mergeStat" />
</bean>
<!-- myBatis文件 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<!-- 自动扫描entity目录, 省掉Configuration.xml里的手工配置 -->
<property name="mapperLocations" value="classpath:com/lcl/*/mapping/*.xml" />
</bean>
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.lcl.*.dao" />
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
</bean>

(3).引入config.properties属性文件。

文件内容如下：

driverClassName=com.mysql.jdbc.Driver
validationQuery=SELECT 1
jdbc_url=jdbc:mysql://localhost:3306/maven-ssm?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull
jdbc_username=long
jdbc_password=long

(4).测试代码。

LoginController.java—Controller类

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import com.lcl.sys.service.LoginService;
@Controller
public class LoginController {
@Autowired
private LoginService loginService;
@RequestMapping(value="/login")
@ResponseBody
public List<Test> doLogin(){
//String str = loginService.Login("login");
List<Test> list = loginService.selectTestAll();
for(Test obj:list){
System.out.println(obj.toString());
}
return list;
}
}

LoginService.java—Service接口

public interface LoginService {
public String Login(String info);
public List<Test> selectTestAll();
}

LoginServiceImp—Service接口实现类

import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.lcl.sys.dao.TestMapper;
import com.lcl.sys.model.Test;
import com.lcl.sys.service.LoginService;
@Service(value="loginService")
public class LoginServiceImp implements LoginService {
@Autowired
private TestMapper testMapper;
public String Login(String info) {
return info;
}
public List<Test> selectTestAll() {
return testMapper.selectTestAll();
}
}

TestMapper.java—dao接口

import java.util.List;
import com.lcl.sys.model.Test;
public interface TestMapper {
List<Test> selectTestAll();
}

Test.java—实体类

public class Test {
private Integer id;
private String author;
private String text;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getAuthor() {
return author;
}
public void setAuthor(String author) {
this.author = author == null ? null : author.trim();
}
public String getText() {
return text;
}
public void setText(String text) {
this.text = text == null ? null : text.trim();
}
@Override
public String toString() {
return "[Id:"+this.getId()+"Author:"+this.getAuthor()+"Text:"+this.getText()+"]";
}
}

TestMapper.xml—sql配置文件

<mapper namespace="com.lcl.sys.dao.TestMapper" >
<resultMap id="TestBaseResultMap" type="com.lcl.sys.model.Test" >
<id column="Id" property="id" jdbcType="INTEGER" />
<result column="author" property="author" jdbcType="VARCHAR" />
<result column="text" property="text" jdbcType="VARCHAR" />
</resultMap>
<select id="selectTestAll" resultMap="TestBaseResultMap"  >
select
Id, author, text
from test
</select>
</mapper>
