从头搭建Spring Boot(二) eclipse

整合spring security,在pom.xml 新增

<!-- 开启spring-security的支持 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>

<!-- 添加对thymeleaf的支持 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

可以查看依赖关系,发现spring-boot-starter-thymeleaf下面已经包括了spring-boot-starter-web,所以可以把spring-boot-starter-web的依赖去掉.

 <!-- 添加对spring-cache的支持 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-cache</artifactId>
        </dependency>

我的pom.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

创建com.lhrq.common目录，在common目录下创建config目录，在config目录下创建文件WebMvcConfig.java，MapperScannerConfig.java, DataSourceConfig.java

import org.springframework.context.annotation.Configuration;
import org.springframework.util.ResourceUtils;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;

@Configuration
public class WebMvcConfig extends WebMvcConfigurationSupport {

/**
* 重写方法描述：实现在url中输入相应的地址的时候直接跳转到某个地址
* @param registry
*/
@Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/login").setViewName("login");
registry.addViewController("/error").setViewName("error");
}

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {

registry.addResourceHandler("/templates/**").addResourceLocations(ResourceUtils.CLASSPATH_URL_PREFIX+"/templates/");
registry.addResourceHandler("/static/**").addResourceLocations(ResourceUtils.CLASSPATH_URL_PREFIX+"/static/");
super.addResourceHandlers(registry);
}

}

MapperScannerConfig 文件代码：(扫描接口DAO)

import org.mybatis.spring.mapper.MapperScannerConfigurer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class MapperScannerConfig {

@Bean
public MapperScannerConfigurer mapperScannerConfigurer() {
MapperScannerConfigurer mapperScannerConfigurer = new MapperScannerConfigurer();
mapperScannerConfigurer.setBasePackage("**.dao");
mapperScannerConfigurer.setSqlSessionFactoryBeanName("sqlSessionFactory");
return mapperScannerConfigurer;
}
}

数据链接资源 DataSourceConfig代码： 

import java.beans.PropertyVetoException;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.Environment;

import com.mchange.v2.c3p0.ComboPooledDataSource;

@Configuration
public class DataSourceConfig {
@Autowired
private Environment env;

@Bean(name="dataSource")
public ComboPooledDataSource dataSource() throws PropertyVetoException {
ComboPooledDataSource dataSource = new ComboPooledDataSource();
dataSource.setDriverClass(env.getProperty("jdbc.driverClassName"));
dataSource.setJdbcUrl(env.getProperty("jdbc.url"));
dataSource.setUser(env.getProperty("jdbc.username"));
dataSource.setPassword(env.getProperty("jdbc.password"));
dataSource.setMaxPoolSize(20);
dataSource.setMinPoolSize(5);
dataSource.setInitialPoolSize(10);
dataSource.setMaxIdleTime(300);
dataSource.setAcquireIncrement(5);
dataSource.setIdleConnectionTestPeriod(60);

return dataSource;
}
