spring source code 5 Import idea2019 three point five

prepare

Download idea2019 3.5 install and activate (see the compressed package sent by brother chicken in the group for specific steps).
Pull spring 5 3.5 source code (tips: it is recommended to start with Star and then Forked, and then go back to the project warehouse of your account and then pull): https://gitee.com/hhf1237/spring-framework
Download jdk15 and unzip: https://pan.baidu.com/s/1m8gwlKJ818Q6sjvZPSg9iQ Extraction code: tm9n (tips: jdk 11 and above are ok). You don't need to configure environment variables, just keep your jdk8.
Download gradle, version: gradle-6.4-rc-4: https://services.gradle.org/distributions/ (tips: the gradle version should be between 5.6 and 6.5, which can be consistent with me). Configure the environment variable (variable name: GRADLE_HOME).

Check the environment variable: gradle -v

Configure acceleration (optional)

Gradle's jar package was also downloaded from maven warehouse.

Install init. In the gradle installation directory D folder, put an init Gradle file (copy and paste in, remember to save).

start

import source code

Modify the configuration to: distributionUrl=https://services.gradle.org/distributions/gradle-6.4-rc-4-bin.zip (tips: modify according to the gradle version. Remember to save and configure the environment variable).
Open idea2019 3.5. Open an existing project casually.
File->New->Project from Existing Sources...

Find the file location of the source code and select the top-level build Gradle, the top-level build Gradle, the top-level build Gradle (say something important three times).
Click: This Window or New Window, you can also click Cancel completely, and then there will be a loaded window. Click Cancel immediately, click Cancel immediately, and click Cancel immediately (important things need to be said three times).
Set gradle and jdk of idea (see the figure for specific operation)
Build (see the figure for specific operation)
wait...
- It is suggested to have a meal and flirt with your sister.
import success
Setting up Java Compiler
Set project SDK

Modify the spring context module configuration

dependencies {
	compile(project(":spring-aop"))
	compile(project(":spring-beans"))
	compile(project(":spring-core"))
	compile(project(":spring-expression"))
//	optional(project(":spring-instrument"))
	compile(project(":spring-instrument"))
    ....
}

Precompiled spring core module
compiler success
Add dependency

Create a test module
- The project name, path and other information will be handled by yourself, and then click Finish to start.
Add dependency
Do whatever you want with the rest of the spring. I don't understand. It's recommended to click the X in the upper right corner. Bye.

aop

First, confirm that there are relevant jar package dependencies in the figure below. By default, there will be automatically after precompiling the spring core module. If there is no need to add manually, the method of adding will be described below.

If there is no jar dependency, you need to add it manually:
Download and install AspectJ support: https://www.eclipse.org/aspectj/downloads.php
- Download AspectJ 1.9.5
- Use the cmd command to cd to the downloaded directory
- In the command window, enter Java - jar aspectj-1.9.5 Jar installation
- Select the root directory of the jdk where we need to compile the spring source code
- Installation directory of AspectJ (remember the location, which will be used later)
- Install AspectJ plug-in in idea, and restart idea after successful installation.
- Change compiler
- Add AspectJ to the main of spring AOP and spring aspects
- Build again (don't worry about stupid kt errors)
- Create an aop test module, add dependencies, refresh and load the module.
```
dependencies {
    compile(project(":spring-context"))
    compile(project(":spring-aspects"))
}
```
- The rest of the spring aop can be used as you like. If you don't understand, it's recommended to click the X in the upper right corner. Bye.

transaction

Create a new module and add dependencies

dependencies {
    compile(project(":spring-context"))
    compile(project(":spring-jdbc"))

    implementation group: 'mysql', name: 'mysql-connector-java', version: '5.1.49'
    implementation group: 'com.alibaba', name: 'druid', version: '1.2.8'
    testCompile group: 'junit', name: 'junit', version: '4.12'
}

Configuration class

package com.qqs.tx;

import com.alibaba.druid.pool.DruidDataSource;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;

@EnableTransactionManagement
public class TxConfiguration {
	/**
	 * Configure the data source (account, password and url are self configured)
	 * @return

	@Bean
	public DataSource dataSource(){
		DruidDataSource dataSource = new DruidDataSource();
		dataSource.setUsername("admin");
		dataSource.setPassword("admin");

		dataSource.setUrl("jdbc:mysql://localhost:3306/spring");
		return dataSource;
	}

	@Bean
	public JdbcTemplate jdbcTemplate(){
		return new JdbcTemplate(dataSource());
	}

	/**
	 * Configure transaction manager
	 * @return
	 */
	@Bean
	public PlatformTransactionManager transactionManager(){
		return new DataSourceTransactionManager(dataSource());
	}
}

Note: mysql version is 5.7. If it is mysql 8.0 0 please refer to the information and configure the url parameter by yourself.

The rest of the business classes are handled by themselves. If you don't understand, it is recommended to click the X in the upper right corner. Bye.

web

Create a new module and add dependencies.

compile(project(":spring-webmvc"))
optional group: 'javax.servlet', name: 'javax.servlet-api', version: '3.1.0'

Root container configuration class

@Configuration
@ComponentScan(value = "com.qqs.mvc",excludeFilters = {
		@ComponentScan.Filter(type = FilterType.ANNOTATION,classes = {Controller.class})
})
public class RootConfiguration {
}

web ioc container configuration class

@ComponentScan(value = {"com.qqs.mvc"},includeFilters = {
		@ComponentScan.Filter(type = FilterType.ANNOTATION,classes = {Controller.class})
},useDefaultFilters = false)
public class AppConfiguration {
}

WebAppInitializer

package com.qqs.mvc;

import com.qqs.mvc.config.AppConfiguration;
import com.qqs.mvc.config.RootConfiguration;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class MyWebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
	/**
	 * Gets the configuration class of the root container
	 * @return
	 */
	@Override
	protected Class<?>[] getRootConfigClasses() {
		return new Class[]{RootConfiguration.class};
	}

	/**
	 * Get the configuration class of the web container
	 * @return
	 */
	@Override
	protected Class<?>[] getServletConfigClasses() {
		return new Class[]{AppConfiguration.class};
	}

	/**
	 * Get the mapping information of DispatcherServlet
	 * @return
	 */
	@Override
	protected String[] getServletMappings() {
		return new String[]{"/"};
	}
}

WebMvcConfigurer (spring MVC custom configuration function)

package com.qqs.mvc.config;

// import com.qqs.mvc.Interceptor.MyHandlerInterceptor;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.*;

@EnableWebMvc // Enable the spring MVC custom configuration function
@Configuration
public class MyWebMvcConfigurer implements WebMvcConfigurer {
	@Override
	public void configureViewResolvers(ViewResolverRegistry registry) {
		// Default JSP without parameters ("/ WEB-INF /,". JSP ")
		registry.jsp("/WEB-INF/views/",".jsp");
	}

	@Override
	public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
		// Static resources
		configurer.enable();
	}

	@Override
	public void addInterceptors(InterceptorRegistry registry) {
		// Configuring Interceptors 
		// registry.addInterceptor(new MyHandlerInterceptor()).addPathPatterns("/**");
	}
}

Business classes and tomcat can be done as they were before they were run. Please don't Baidu yourself.
