Mybatis优化

我们在使用mybatis的时候，需要注意mybatis的性能，怎么才能快速提高查询，在编写实体Bean 需要生成getXXX 和setXXX方法 ,在设置settings也需要注意一些选项：

需要在实体Bean里面添加getXXX 和setXXX方法：
比如：UserInfo.java
public class UserInfo {
private Integer userId;
private String userName;
private String userSex;
private Integer userAge;
public Integer getUserId() {
return userId;
}
public void setUserId(Integer userId) {
this.userId = userId;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getUserSex() {
return userSex;
}
public void setUserSex(String userSex) {
this.userSex = userSex;
}
public Integer getUserAge() {
return userAge;
}
public void setUserAge(Integer userAge) {
this.userAge = userAge;
}
在设置mybatis-config.xml配置文件里面settings信息：
<configuration>
<settings>
<setting name="cacheModelsEnabled" value="true"/>
<setting name="lazyLoadingEnabled" value="true"/>
<setting name="enhancementEnabled" value="true"/>
<setting name="errorTracingEnabled" value="true"/>
<setting name="maxSessions" value="500"/>
<setting name="maxTransactions" value="200"/>
<setting name="maxRequests" value="1024"/>
<setting name="useStatementNamespaces" value="true"/>
</settings>
<environments default="developments">
<environment id="mysql">
<transactionManager type="JDBC"></transactionManager>
<dataSource type="POOLED">
<property name="driver" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://127.0.0.1:3306/test" />
<property name="username" value="root" />
<property name="password" value="root" />
</dataSource>
</environment>
</environments>
<mappers>
<mapper resource="com/test/domain/userinfo.xml" />
</mappers>
</configuration>
